On the performance of a nanocatalyst-based Direct Ammonia Alkaline Fuel Cell (DAAFC) under microgravity conditions for water reclamation and energy applications

Completed TRL 7 (started at 6, targeting 7)

Description

This project is a continuation of T0040-P. Recent advances in anion exchange membranes have made Direct Ammonia Alkaline Fuel Cell (DAAFC) one of the most promising and attractive fuel cell systems for water reclamation and energy production in space missions. Although recent studies have proposed direct ammonia fuel cells as the next generation of power devices, critical knowledge about the performance of DAAFC under microgravity conditions has not been addressed. The objective of this research is to assess the performance of a DAAFC using nanotechnology-based electrodes to enhance the electrochemical decomposition of ammonia under micro-gravity conditions.

Benefits

Studying the effects of microgravity on the performance of a direct ammonia alkaline fuel cell may lead to advances in space-flight water reclamation and energy production, which will benefit future NASA missions.

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.
