Dimensionally Stable Membrane for High Pressure Electrolyzers, Phase II

Completed

Description

Utilizing high strength polymers with controlled pore dimensions as a support, a customized membrane electrode assembly (MEA) can be generated for NASA's electrolyzer and fuel cell stacks that has optimized electrochemical performance with greatly improved mechanical properties enabling high pressure (>1000 psi) operation. The overall objective is to optimize DSM-based MEAs for a NASA lunar application. This will be accomplished through six tasks; 1. Extending GES's gas crossover and chemical degradation mitigation strategies to DSMs 2. Improving DSM with better ionomer; 3. Optimize the anode; 4. Optimize DSM MEAs for H2/O2 fuel cells. 5. Update GES model for electrolyzer and fuel cell performance. 6. Use model to select optimal DSM for lunar electrolyzer application and generate MEAs for full-size stack.

How to get involved

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
