PURPOSE:To obtain a micro fuel cell by connecting current collecting walls in series to each other between unit cells each comprised by current collecting walls and cell assembling bodies, and then combining plural cell units together to form a single cell. CONSTITUTION:A fuel cell 10 includes four fuel electrodes 44 each comprising a platinum catalyst retained in a carbon paper, and four air electrodes 46. A pole assembly comprising an ion conductive resin film 45 sandwiched between the fuel electrodes 44 and the air electrodes 46 and integrally laminated, and a carbon air electrode current collecting plate 47 having a number of air through holes 48 are both sandwiched and retained in a laminated state. In this case, four electrode collectors are each single cell and are connected in series to each other by a lead wire 51. The lead wire 51 is actually connected to a fuel electrode current collecting plate 42 and the air electrode current collecting plate 47, and its wiring is carried out via plural holes formed through a disc 25 and a space existing between the plate 25 and a cover 30. A micro fuel cell is thus obtained. |
