Abstract
A fuel cell system operates under at least one of the conditions of no humidity or high temperature, and an operating method thereof, are characterized in that a fuel cell has a fuel gas flow path and an oxidant gas flow path arranged such that fuel gas and oxidant gas flow in opposite directions, a determining apparatus that determines the amount of water near the oxidant gas flow path inlet, and a fuel gas control apparatus which increases the amount of water near the oxidant gas flow path inlet by increasing the fuel gas flowrate and/or reducing the fuel gas pressure if it is determined in the determining apparatus that the amount of water near the oxidant gas flow path inlet is insufficient.
