PROBLEM TO BE SOLVED: To provide a fuel cell system of good efficiency. SOLUTION: The fuel cell system comprises a fuel cell stack (1) where the anode gas containing hydrogen and the cathode gas containing oxygen are supplied to respective electrodes for power generation, an ejector (6) which is interposed on the way of a path to supply the anode gas to an anode, and a circulation path (5b) which guides a part of the anode waste gas discharged from the anode into the ejector (6). By providing a circulation pump (11) to the circulation path, the anode waste gas is stably circulated across the entire operation area of the fuel cell stack. |
