<P>PROBLEM TO BE SOLVED: To achieve insurance of good electrical connectability and reduction of contact resistance in addition to a tracking ability to thermal stress in a fuel cell unit of a disk type having a gas chamber of a bag closed structure. <P>SOLUTION: The fuel cell unit U of a disk type, having a flat gas chamber 10 locked out at an outer periphery portion between a single cell 1 and a separator plate 2, includes current collection plates 3 and 4 formed by providing a plurality of elastic protrusions 9 on a surface of one side and by making a surface of another side flat, wherein the flat surfaces of the current collecting plates 3 and 4, and at least a surface of the separator plate 2 of a single cell 1 side are integrally joined, and the elastic protrusions 9 are crimped to the single cell 1. Thereby, the insurance of good electrical connectability and reduction of contact resistance are achieved in addition to the good tracking ability to thermal stress. <P>COPYRIGHT: (C)2010,JPO&INPIT |
