This final report summarizes a 3-phase program performed from March 2000 through September 2003 with a particular focus on Phase III. The overall program studied TMI's reversible solid oxide stack, system concepts, and potential applications. The TMI reversible (fuel cell-electrolyzer) system employs a stack of high temperature solid-oxide electrochemical cells to produce either electricity (from a fuel and air or oxygen) or hydrogen (from water and supplied electricity). An atmospheric pressure fuel cell system operates on natural gas (or other carbon-containing fuel) and air. A high-pressure reversible electrolyzer system is used to make high-pressure hydrogen and oxygen from water and when desired, operates in reverse to generate electricity from these gases
