Abstract:
1. A method of operating a fuel cell power generation system which heats a reformer with an exhaust gas of a fuel cell module, wherein the reformer has a structure of a three-fluid heat exchanger which includes a flow channel for to-be-reformed gas having a reformation catalyst, a flow channel for the exhaust gas and a flow channel for fluid whose temperature is higher or lower than temperature of the exhaust gas, the flow channel for the to-be-reformed gas and the flow channel for the fluid whose temperature is higher or lower than temperature of the exhaust gas being adjacent to each other with a first segregation wall located therebetween, the method comprising a step of: controlling temperature of the reformer by supplying to the three-fluid heat exchanger of the reformer the fluid whose temperature is higher of lower than temperature of the exhaust gas in response to temperature or load of the fuel cell module.
