NOVELTY - Fuel cell includes pair of terminals positioned at respective end of cell stack. One of the terminals has an accommodating portion for accommodating the pipe member, and a gap is formed between a flange portion of the pipe member and a cell stack under a zero contacting condition when a pressure load of the pair of the pressure plates is zero.    USE - As fuel cell.    ADVANTAGE - The inventive fuel cell has a corrosion resistant material for preventing increase in contact resistance in a case where an inlet/outlet hole is covered with corrosion resistant member.    DETAILED DESCRIPTION - Fuel cell comprises:    (A) cell stack (10) formed by stacking cells, each cell (11) has a membrane electrode assembly having an electrolyte membrane and an electrode provided at each side of the electrolyte membrane, a flow channel for supplying fluid to the electrode, and separators (19, 20) each has a flow path from the flow channel to outside the fuel cell stack;    (B) pair of terminals provided so as one terminal is positioned at one end of the cell stack and the other terminal is positioned at the other end of the cell stack;    (C) pair of pressure plates provided for sandwiching and fastening the cell stack from outside the terminals, each pressure plate includes an inlet/outlet hole connected to the flow path; and    (D) pipe member connected to the flow path.    The pipe member is made of a corrosion resistant material, and includes a pipe portion inserted into the inlet/outlet hole, and a flange portion at the cell stack side of one of the pressure plates. One of the terminals has an accommodating portion for accommodating the pipe member, and a gap is formed between the flange portion of the pipe member and the cell stack under a zero contacting condition when a pressure load of the pair of the pressure plates is zero. Any one of the members of the cell stack and the terminal provided between the pressure plates is in contact with the neighboring member.
