Job Description:

1. Design and develop advanced PFSA membranes by tailoring polymer
architecture and membrane thickness through solution casting and
coating processes to enhance PEM water electrolyzer performance and
durability.
2. Develop advanced structure and composite membranes to balance
conductivity, mechanical strength and gas crossover.
3. Optimize ionomer dispersions: solvent systems, equivalent weight (EW),
solids content, rheology and annealing conditions.
4. Measure proton conductivity (in-plane and through-plane), IEC, water
uptake, swelling, tensile and creep properties.
5. Develop and implement component-level test methodologies to evaluate
and characterize membrane properties, including mechanical, chemical,
thermal, and electrochemical performance.
6. Run accelerated stress tests: Fenton/OCV chemical degradation, fluoride
release rate, mechanical cycling and pressure-differential tests.
7. Use characterization techniques like FTIR, NMR, TGA, DSC, DMA,
SAXS/WAXS, SEM/EDX and XPS to relate structure to performance.
8.



Assess H₂/O₂ crossover and membrane behavior in single-cell and short-
stack electrolyzer tests with the MEA level
9. Transfer lab processes to pilot roll-to-roll casting/coating with process
engineering; define specs and QC methods.
10. Analyze the post operated MEA to identify the failure modes (Thinning,
Pinholes and chemical attack etc.)
11. Qualify advanced membrane technologies through rigorous testing,
reliability assessment, and performance verification under application-
relevant operating conditions.
12. Develop and implement protected work practices for PFSA ionomer handling
and testing.
13. Collaborate with cross-functional teams to translate membrane
performance requirements into robust qualification plans and acceptance
criteria.
