The present invention is a power system using a reformer/fuel cell arrangement as the primary source of DC power. The reformer is operated on either natural gas or propane. A backup source of power consumes hydrogen which is diffused from a solid medium. On an as-needed basis, the medium is reacted to release hydrogen gas which is consumed by a fuel cell to generate backup DC power. The system also includes Lithium-Metal-Polymer batteries which are used for both bridging and backup purposes.
