What does an electrolyzer stack engineer do?

An Electrolyzer Stack Engineer is responsible for designing, developing, and optimizing the core components of electrolyzers, which are devices that use electricity to split water into hydrogen and oxygen. Their work involves selecting materials, designing stack architecture, testing prototypes, and improving performance and durability. Electrolyzer Stack Engineers collaborate with multidisciplinary teams to scale up production, reduce costs, and ensure the stacks meet safety and efficiency standards for applications in green hydrogen production and renewable energy.

What are the key skills and qualifications needed to thrive as an electrolyzer stack engineer?

To thrive as an Electrolyzer Stack Engineer, you need a strong background in electrochemistry, materials science, and mechanical or chemical engineering, typically supported by a relevant engineering degree. Familiarity with CAD software, simulation tools, and stack performance testing equipment is crucial, along with knowledge of industry standards and safety protocols. Analytical thinking, problem-solving abilities, and effective teamwork are essential soft skills for optimizing designs and collaborating with multidisciplinary teams. These skills are vital to developing efficient, reliable electrolyzer stacks that advance hydrogen production technologies and meet industry demands.

What are some typical challenges electrolyzer stack engineers face when scaling up designs from prototype to mass production?

Electrolyzer Stack Engineers often encounter challenges related to material durability, manufacturing consistency, and system integration as they move from prototype to mass production. Ensuring that components such as membranes and catalysts perform reliably at scale requires close collaboration with materials scientists and production teams. Additionally, refining the stack design to optimize efficiency while reducing costs is an ongoing focus, and maintaining quality control during high-volume manufacturing can be demanding. Successful engineers proactively address these issues by implementing rigorous testing protocols and working collaboratively across multidisciplinary teams.

What is the difference between Electrolyzer Stack Engineer vs Electrolyzer System Engineer?

AspectElectrolyzer Stack EngineerElectrolyzer System Engineer
CredentialsEngineering degree, certifications in electrochemical systemsEngineering degree, certifications in renewable energy systems
Work EnvironmentDesign, testing, and development of electrolyzer stacks in labs or manufacturingSystem integration, operation, and troubleshooting of electrolyzer systems
Industry UsageFocused on stack components within hydrogen production facilitiesOversees entire electrolyzer systems in renewable energy plants

Electrolyzer Stack Engineers specialize in developing and testing electrolyzer stacks, focusing on component performance. In contrast, Electrolyzer System Engineers handle the overall system operation, integration, and maintenance. Both roles are essential in hydrogen production, but they differ in scope and responsibilities.

Job description

R&D Test Engineer

Apply now Job no: 502926
College / VP Area: Research Office
Work type: Staff
Location: Newark, DE
Categories: Engineering, Research & Laboratory, Full Time

Pay Grade: 32E
 
Context of Job:
 
The University of Delaware, in close collaboration with industry, academic, and national laboratory partners including Chemours, Plug Power, West Virginia University, and the National Laboratory of Rockies (NLR), has established the Center for Clean Hydrogen (CCH). The Center's mission is to accelerate the transition to a clean energy economy through advanced research and development in green hydrogen production, fuel cells, and carbon capture technologies. CCH operates state-of-the-art research facilities and large-scale test infrastructure to support both fundamental research and industry-facing development.

The Center is seeking a highly motivated and versatile Engineer to support cutting-edge hydrogen technology programs in a fast-paced, adaptive research environment. The Engineer will play a critical role in the design, setup, commissioning, and operation of hydrogen research infrastructure at CCH. This is a hands-on position requiring strong technical breadth, rapid learning ability, and the capacity to manage multiple projects independently with minimal supervision. The successful candidate will work closely with faculty, research staff, students, and external partners to deliver high-impact research outcomes on aggressive timelines.
 
Major Responsibilities:
  • Support the setup, commissioning, and operation of large-scale electrolyzer test stands, including a 150 kW PEM electrolyzer test stand and a 300 kW AEM electrolyzer test stand.
     
  • Support the design, assembly, and operation of segmented electrolyzer cells and stacks with integrated inline diagnostics.
  • Establish and operate advanced analytical and diagnostic equipment in support of inline degradation and performance analysis of electrolyzer, including ICP-MS, XRF, Ion Chromatography (IC), SEM, Raman spectroscopy, and FTIR.
  • Operate and support research activities using spark-ablation based nanoparticle deposition equipment (VS Particle P1 nanoprinter).
  • Design and build new laboratory-scale electrolyzer and electrochemical test stands.
  • Contribute to system troubleshooting, performance optimization, and operational efficiency improvements.
  • Assist with procurement, installation, and commissioning of new laboratory equipment.
  • Ensure compliance with laboratory safety standards, with particular emphasis on hydrogen safety practices.
     
Qualifications:
  • Bachelor's degree in Chemical Engineering, Mechanical Engineering, Mechatronics Engineering, or a closely related discipline and six years of relevant industrial experience.
     
  • Experience with hydrogen-related research or industrial systems; experience with industrial-scale fuel cell or electrolyzer plants is strongly preferred.
  • Strong understanding of electrolyzer systems, including cell architecture, materials, stack design, and balance-of-plant (BoP) components such as pumps, heat exchangers, valves, and sensors.
  • Solid skills in 3D CAD modeling for electrolyzer cell and stack design, with basic understanding of CNC machining and component fabrication. Hands-on machine shop experience is a plus.
  • Working knowledge of electrical engineering and control systems, including the ability to read and create basic electrical diagrams.
  • Mechatronics engineering background and experience on PLC-based control systems are highly desirable.
  • Experience operating or working with analytical and characterization equipment commonly used in electrochemical and materials research.
  • Good coding skills, with proficiency in Python for data analysis and visualization; demonstrated ability to utilize AI coding tools effectively.
  • Strong understanding of laboratory safety practices, particularly those related to hydrogen systems.
  • Experience with hydrogen-related codes, standards, and certification processes (e.g., UL, NFPA) is a plus.
  • Rapid learner with a genuine interest in acquiring new technical skills preferred.
  • Highly self-motivated self-starter capable of working independently with minimal direct supervision preferred.
  • Proven ability to manage multiple priorities and deliver results on short timelines preferred.
  • Strong focus on operational efficiency, reliability, and continuous improvement preferred.
  • Excellent teamwork and communication skills in a dynamic, collaborative environment preferred.
