A method and a system for the co-production of electricity and hydrogen fuel are provided. The system may include a fuel conditioning unit, two or more iron / iron oxide beds and a high temperature electrochemical generator. In one embodiment, a reduction bed contains iron oxides. A hydrocarbon fuel, such as natural gas, is conditioned to carbon dioxide and hydrogen by the reduction bed. The conditioned fuel is then converted electrochemically to generate electricity in a fuel cell. Operating simultaneously is an oxidation bed that oxidizes elemental iron to iron oxides and produces hydrogen. The oxidation bed may previously have served as the reduction bed. The hydrogen thus produced is sufficiently pure to be used in a refueling application. The heat necessary for the endothermic reduction may be provided by the high temperature electrochemical generator. The two beds may operate concurrently or sequentially, and alternate their roles when their reactants are partially exhausted.
