About this role
Job Description:
Key Responsibilities
• Lead the integration of multi-layer electrolyzer stack components (MEA, PTL, gaskets, bipolar plates) to ensure proper fit, function, and performance. • Define and optimize stack compression strategy, including compression windows, tolerances, and assembly sequences. • Analyse and control load transfer mechanisms across layers under hydraulic pressing and bolt torquing conditions. • Ensure uniform contact pressure distribution to balance sealing integrity, electrical contact resistance, and component durability. • Evaluate mechanical behaviour of layers (elastic/plastic deformation, creep, stress relaxation) under assembly and operating conditions. • Improve pressure handling capability of the stack, including resistance to leakage, deformation, and mechanical failure. • Correlate mechanical compression with electrochemical performance (efficiency, voltage losses, degradation). • Develop and use FEA models to predict stress, strain, and contact pressure distribution across the stack. • Design and execute validation tests (compression mapping, torque-tension, leak and pressure cycling tests). • Collaborate cross-functionally to ensure design robustness, manufacturability, and scalability of stack integration solutions.
Required Qualifications
• B.E or M.E in Mechanical or Chemical or Material science background • 5 to 10 years of experience required in Electrolyzer, fuel cell, or similar electrochemical stack systems or EV systems • Mechanical integration of multi-layer assemblies. • Strong understanding of: • Stack compression mechanics • Load transfer through layered structures • Torque-preload relationships in bolted joints
• Experience with: • Hydraulic press assembly processes • Gasket sealing mechanics and material behaviour • Porous transport layer (PTL) compression characteristics
• Ability to interpret: • Stress-strain curves • Contact mechanics • Nonlinear material behaviour. We are seeking a highly skilled Senior Stack Integration Engineer to lead the integration and optimization of electrolyzer stack architectures. This role focuses on ensuring robust mechanical, electrochemical, and pressure-performance integration across stack layers to achieve superior durability, efficiency, and operability.
The ideal candidate will have deep expertise in load transfer mechanisms, compression behaviour, and torque-induced sealing performance, along with a strong understanding of electrochemical stack physics.
