Hydrogenics Corp (HYGS) has sold a light weight 5kW hydrogen/oxygen Proton Exchange Membrane (PEM) fuel cell stack to the NASA Glenn Research Center, which will use it in an experimental closed cycle hydrogen-oxygen regenerative fuel cell. This type of system can be used for energy storage in places where oxygen is not easily available, such as very high altitude, space or underwater environments. NASA will use this stack as part of its research program to understand how the regenerative fuel cell will operate in future aerospace applications. [ more ]
