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.
Ohmium is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
