Dimensionally Stable Membrane for High Pressure Electrolyzers, Phase II

Completed Technology Project

Project Description

Dimensionally Stable Membrane for High Pressure Electrolyzers, Phase II
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. More »
