Abstract:
1. A fuel cell system comprising: a fuel cell that includes a plurality of stacked cells for generating power by an electrochemical reaction between fuel gas and oxidant gas; a pressure adjusting valve that is disposed between a fuel tank and a fuel gas inlet of the fuel cell for adjusting a gas pressure at the fuel gas inlet; a gas circulation pump that circulates reacted fuel gas from a fuel gas outlet of the fuel cell to the fuel gas inlet; a cell voltage acquisition unit that acquires a voltage of each of the cells; and a controller programmed to perform a start-up and a stop of the gas circulation pump and adjusts an open degree of the pressure adjusting valve, wherein the controller comprises: a clog determination unit that, at a start of the fuel cell, a clog elimination unit that removes the clog of the fuel gas flow channel when the clog determination unit has determined that the clog is present in the fuel gas flow channel, by
