Job description

Job Description

• Prepare test plans, test protocols and procedures for performance characterization, durability, accelerated stress and dynamic cycling tests.
• Support commissioning of the test system, including verification of sensors, interlocks and safety logic through to final tester acceptance.
• Manage routine calibration and verification of test instruments to ensure measurement accuracy.
• Execute testing and data analysis of PEM electrolyser stacks.
• Adapt quickly to different test types, tester designs and functionalities.
• Guide test technicians with clear instructions for continuous monitoring of stack and system operation and performance.
• Process and analyse large multi-channel datasets from operating stacks, including individual cell voltages, stack voltage/current, temperatures, pressures, flow rates, etc.
• Define, calculate and track key performance indicators such as cell voltage spread, energy consumption, efficiency, degradation rate and gas crossover.
• Perform cell-to-cell and stack-to-stack statistical analysis and correlate test results with stack build data to identify root causes of variation.
• Perform gas chromatography (GC) analysis and data evaluation to support performance characterisation and identify anomalies and key trends.
• Apply electrochemical characterisation methods for performance evaluation and diagnostics of electrochemical systems.
• Collaborate with cross-functional engineering teams to analyse and correlate stack and system performance.
• Lead root cause analysis (RCA) of system failure modes and oversee troubleshooting and maintenance of the testers.
• Record and manage test deviations, non-conformances and corrective actions and provide feedback to stack design and materials teams.
• Prepare test reports, technical summaries and presentations for internal reviews and project updates.
• Drive continuous improvement initiatives to enhance testing efficiency, quality and reliability.
• Ensure compliance with all health, safety and environmental regulations.
