Abstract:
1. A power source system, comprising: a chemical reaction unit which receives a supply of fuel for power generation to produce a gas for power generation; a generator unit which receives a supply of the gas for power generation, reacts a part of the gas for power generation to generate power, and ejects an unreacted part of the gas for power generation as an offgas; a heating apparatus, provided in the chemical reaction unit, which receives a supply of the offgas and a fuel for combustion, and sets the chemical reaction unit to a predetermined temperature by a heat quantity generated by a combustion reaction using a combustion component in the offgas and the fuel for combustion; a flow meter which measures a flow rate of the gas for power generation supplied to the generator unit; a calculator which calculates a residual hydrogen quantity of the combustion component in the offgas based on a value of the flow rate of the gas for power generation supplied to the generator unit, and a value of power generated by the generator unit; a supply quantity adjuster which adjusts a quantity of the fuel for combustion to be supplied to the heating apparatus; and a controller which controls the heat quantity generated by the heating apparatus by controlling the supply quantity adjuster; wherein the controller calculates a difference value between (i) a value of the residual hydrogen quantity obtained by the calculating of the residual hydrogen quantity by the calculator and (ii) a previous value of the residual hydrogen quantity obtained by the calculating of the residual hydrogen quantity by the calculator, and the controller controls the supply quantity adjuster based on a setting value of the supply quantity adjuster corresponding to the difference value so that a next difference value becomes zero.
