FUEL CELL SYSTEM AND METHOD FOR MANUFACTURING THE SAME

An opening is formed at an end portion of a stack case that houses a fuel cell stack. A unit cell constituting a fuel cell stack is provided with a cell voltage detection terminal at a position facing an opening. A conductor extends from the cell voltage detection terminal. The opening is covered with a porous cover that is formed with a plurality of through-holes. The porous cover is formed with an annular protrusion on an end face facing the cell voltage detection terminal. The annular protrusion is located among the plurality of through-holes.
