FUEL CELL STACK AND FUEL CELL COGENERATION SYSTEM EQUIPPED WITH FUEL CELL STACK

摘要

A fuel cell cogeneration system of the present invention includes: a cell (10); a fuel gas discharging manifold (122) which is formed to extend in a thickness direction of the cell (10) and through which an anode off gas unconsumed in an anode (2A) flows; an oxidizing gas discharging manifold (124) which is formed to extend in the thickness direction of the cell (10) and through which a cathode off gas unconsumed in a cathode (2B) flows; and a cooling medium discharging manifold (126) which is formed to extend in the thickness direction of the cell (10) and through which an off cooling medium having recovered heat from the cell (10) flows, and the fuel gas discharging manifold (122) and/or the oxidizing gas discharging manifold (124) are formed between the cooling medium discharging manifold (126) and a separator end closest to the cooling medium discharging manifold (126).
