PROBLEM TO BE SOLVED: To provide a hydrogen fuel cell in which hydrogen can be circulated and reused.SOLUTION: The hydrogen fuel cell includes an anode module 10, a cathode module 20, a catalyst layer 30, a proton exchange membrane 40, a hydrogen supply device 50, a hydrogen occlusion metal layer 60, and a hydrogen absorbing device 70. The catalyst layer 30 is interposed between a first electrode plate 11 and the proton exchange membrane 40, and is electrically conducted with the first electrode plate 11. The hydrogen supply device 50 isolates hydrogen from the catalyst layer 30 and makes it into an electron and a hydrogen proton by supplying the hydrogen to the catalyst layer 30. The hydrogen occlusion metal layer 60 is interposed between the proton exchange membrane 40 and a second electrode plate 21, and is electrically conducted with the second electrode plate 21. After the hydrogen proton passes through the proton exchange membrane 40, electrons coming from the second electrode plate 21 are coupled and reacted with the hydrogen occlusion metal layer 60 into a hydrogenated alloy. The hydrogen absorbing device 70 absorbs hydrogen from the hydrogenated alloy, and feeds it to a storage tank 71 for circulation and reuse. |
