COLLECTOR PLATE FOR FUEL CELL, FUEL CELL STACK, FUEL CELL SYSTEM, AND MANUFACTURING METHOD OF FUEL CELL SYSTEM

PROBLEM TO BE SOLVED: To provide a technology for suppressing increase of conductive resistance in extracting power that is collected from a fuel cell stack.SOLUTION: A collector plate for fuel cell comprises: a collector part for collecting power that is generated by a fuel cell; and a terminal part for outputting power that is collected by the collector part, a bus bar being fitted to the terminal part. The terminal part comprises: a terminal part body that is electrically connected with the collector part; a first screw part that is fixed to the terminal part body; a second screw part which is threaded with the first screw part for fixing one end of the bus bar to the terminal part; and a projection provided on the same surface of the terminal part body on which the first screw part is provided. The projection is disposed at a rear side of the second screw part in a direction of rotation when fastening the second screw part into the bus bar in the case where one end of the bus bar is fixed to the terminal part and another end of the bus bar is fixed to other equipment.SELECTED DRAWING: Figure 5 【課題】燃料電池スタックから集電した電力を取出す際の導電抵抗の増大を抑制する技術を提供する。【解決手段】燃料電池が発電した電力を集電する集電部と、集電部にて集電した電力を出力するための端子部であって、バスバーが取付けられる端子部と、を備える、燃料電池用の集電板であって、端子部は、集電部と電気的に接続された端子部本体と、端子部本体に固定された第１のねじ部と、第１のねじ部に螺合してバスバーの一端を端子部に固定する第２のねじ部と、端子部本体の第１のねじ部が設けられた面と同一の面に設けられる突起部と、を備え、突起部は、バスバーの一端が端子部に固定され、バスバーの他端が他の機器に固定された場合に、バスバーに対して、第２のねじ部を締め込む際の第２のねじ部の回転方向後ろ側に配置される。【選択図】図５
