A fuel cell is a device that converts flowing hydrogen (or a hydrogen rich stream) and flowing oxygen (or an oxygen rich stream like air) to produce electricity without combustion. The specific innovation that Infinity has developed reduces the need for moving parts like pumps and blowers and prevents the need for venting the fuel cell. This increases efficiency of the device and NASA likes efficiency when it comes to the power sources for their space missions.
