A hydrogen tank (132, 224, 230, 240) temporarily stores the stream of hydrogen. During a power generation mode, a fuel cell (134, 212) converts the stream of hydrogen gas from the tank into output electrical power by combining the hydrogen with oxygen. An inverter (152, 206) conditions and supplies the electrical power to a local load (110, 300). A controller circuit (140, 204, 336, 340) uses a system parameter to adaptively switch between the storage mode and the power generation mode. In some cases, external power is supplied during the generation and storage of the hydrogen gas from an electrical grid (104, 302) or a local renewable source such as a set of solar panels (120, 304).
