This research put forward a pattern of generation of electric power. We use a PEM Fuel Cell Power Generation System with Methane Reformer to meet the demand of load.Supply of fuel cell using methane reformer hydrogen production to meet the high power demand of the fuel cell,but when the fuel cell power instantaneous demand for larger,make the fuel cell temperature exceeds the operating rang,and we know when the battery temperature is too high,it will caused by proton exchange membrane dehydration,rupture the worst case,the fuel cell will lose their effectiveness,control of temperature in the fuel cell can not be ignored topic. This paper presents a model predictive control strategy,the battery temperature and battery output power controlled by the cooling water flow rate and methane flow rate to ensure that the battery performance and meet the power needs of battery output in a suitable operating point,the model predictive control tunable many parameter settings,and use this controller to eliminate external interference,the result can meet the desired results,the fuel cell can reach a steady state.
