<P>PROBLEM TO BE SOLVED: To provide a fuel cell power generation system in which molar flow rates of fuel and air to be supplied to a fuel cell can be made uniform even if there is a temperature distribution in a power generation module. <P>SOLUTION: In the power generation system provided with a power generation module with a plurality of fuel cells, at least one of passage cross sections of a fuel passage and an air passage is made larger at a central portion of the power generation module and smaller at end portions. Gas can flow easily in the central portion of the power generation module and a gas flowing speed becomes faster. As a result, even if there is a temperature distribution in the power generation module, a molar flow rate of gas to be supplied to the fuel cell can be made uniform. <P>COPYRIGHT: (C)2008,JPO&INPIT |
