Small Business Innovation Research/Small Business Tech Transfer
Advanced Cathode Electrolyzer (ACE), Phase II
Project Description
The proposed innovation is a static, cathode-fed, 2000 psi, balanced-pressure Advanced Cathode Electrolyzer (ACE) based on PEM electrolysis technology. It electrolyzes water vapor supplied to the hydrogen-evolving electrode and eliminates the need to circulate hydrogen and water on the cathode side of the cell. Innovations include the application of Infinity proprietary cell sealing technology to electrolysis to minimize high-pressure seals and the use of innovative passive current-control techniques to eliminate potential hydrogen gas in feedwater chambers. ACE produces hydrogen and oxygen that is free of liquid water droplets without using dynamic product gas/liquid water phase separation and/or other motorized equipment.

Anticipated Benefits
Non NASA commercial applications include recharge of fuel cells for telecom backup power, remote off-grid power, undersea fuel cell systems and aircraft and airship energy storage systems A simple reliable modular electrolyzer, that passively and efficiently generates high pressure hydrogen and oxygen, has wide potential application in future NASA missions. These include lunar and planetary fixed base energy storage, recharge of lunar rovers and portable power fuel cells as well as generation of oxygen for crew life support.
