Abstract

See full text

In order to suppress an increase in electric resistance when retrieving electric power collected from a fuel cell stack, a current collector for a fuel cell is provided. The current collector includes a current collecting portion for collecting electric power generated by the fuel cell, and a terminal portion for outputting the power collected by the current collecting portion. A bus bar is attached to the terminal portion. The terminal portion includes a terminal portion main body, electrically connected with the current collecting portion, a first threaded part fixed to the terminal portion main body, a second threaded part for threadedly engaging with the first threaded part to fix one end of the bus bar to the terminal portion, and a protruded portion provided in the same surface as a surface where the first threaded part of the terminal portion main body is provided. The protruded portion is disposed at a position where the protruded portion contacts the bus bar to stop a rotation of the terminal portion main body accompanying fastening of the second threaded part, when the one end of the bus bar is fixed to the terminal portion in a state where the other end of the bus bar is fixed to another instrument.
