Patent ID: 8507140

Claim:
A hydrogen-recyclable fuel cell comprising: an anode set including a first electrode plate; a cathode set including a second electrode plate; a proton exchange membrane being located between said first electrode plate and said second electrode plate; a catalytic layer being defined between said first electrode plate and said proton exchange membrane, lying against said proton exchange membrane and facing towards said first electrode plate, and forming electrical conductivity with said first electrode plate; a hydrogen delivering device delivering hydrogen to said catalytic layer which ionizes hydrogen to electrons and hydrogen ions, said electrons discharged from said first electrode plate to said second electrode plate while said hydrogen ions moving towards said second electrode plate through said proton exchange membrane; wherein, a hydrogen-storage complex metal layer being defined between said proton exchange membrane and said second electrode plate, said hydrogen-storage complex metal layer lying against said proton exchange membrane and facing towards said second electrode plate and forming electrical conductivity with said second electrode plate; after said hydrogen ions passing through said proton exchange membrane, then said hydrogen ions reacting with said hydrogen-storage complex metal layer and said electrons from said second electrode plate to produce complex metal hydrides; and a hydrogen drawing device being employed to draw hydrogen from said complex metal hydrides for further reuse.
