- 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.
