PROBLEM TO BE SOLVED: To solve the following problem: in a cell assembly unit including a cell assembly, a holding member for holding the cell assembly, and a collector that is electrically connected with the cell assembly and provided in part of the support member, even though an insulating member is disposed between the collector and the holding member, the insulating member is damaged to invite dielectric breakdown.SOLUTION: A cell assembly unit includes: a cell of a fuel cell which generates electricity by using fuel gas and cathode gas; a cell assembly of a fuel cell where a plurality of fuel battery cells are electrically connected to one another; a holding member which encloses and presses the cell assembly of the fuel cell; and a collector which is disposed outside the holding member and extracts electricity from the cell assembly of the fuel cell. A fastening portion is provided to fasten the holding member and the collector to each other. The fastening portion is formed of a fastening portion body and a washer portion to which the fastening portion body is fitted. The washer portion includes a taper portion which presses down the holding member. An insulating inorganic fiber sheet is provided to be held between the holding member and the washer portion. |
