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.
