1. Key Responsibilities

Fuel cell engineers apply chemical, mechanical, and electrical engineering principles to:

• System Design & Modeling: Develop and refine fuel cell stack architectures, balance-of-plant components (compressors, humidifiers), and overall system layouts using CAD and simulation tools.
• Electrochemical Development: Select and characterize membrane materials, catalysts, and electrodes; analyze reaction kinetics and mass-transport phenomena.
• Prototyping & Testing: Build and test fuel cell stacks or complete systems in labs and environmental chambers; collect performance data (voltage, current, efficiency, degradation rates).
• Durability & Degradation Analysis: Conduct accelerated‐life tests, identify failure modes, and develop mitigation strategies to extend system lifespan.
• System Integration: Interface fuel cells with power electronics, battery hybrids, or microgrids; optimize thermal management and control strategies.
• Manufacturability & Scale-Up: Work with suppliers and production engineers to translate lab‐scale designs into manufacturable products; address cost, yield, and quality challenges.
• Safety & Compliance: Ensure safe handling and storage of hydrogen, perform hazard analyses (HAZOP), and comply with relevant codes and standards (e.g., NFPA 2).
• Technical Documentation: Prepare design specifications, test protocols, and regulatory submissions; maintain rigorous version control.

2. Essential Skills & Qualities

Fuel cell engineering demands a blend of multidisciplinary expertise:

• Electrochemistry & Materials Science: Deep knowledge of catalysts, membranes, and electrode‐electrolyte interfaces.
