A structural fuel cell includes a first and a second electrically conductive electrode plate each comprised of a porous, open-cell material. A proton conductive membrane is disposed between the first and second plates, and a skin encloses the electrode plates and membrane. The structural fuel cell is fabricated from high strength materials, and the porous, open-cell material of the electrode plates may comprise a metal foam, a honeycomb structure, or other such expanded structure. The skin may comprise a composite material such as a reinforced polymer. In some instances, the combination of the electrode plates, membrane and skin has a flexural strength between 1-100 MPa, or a flexural stiffness between 0.1-10 GPa.
