Abstract
When a load of a fuel cell to which hydrogen gas is supplied from a fuel reformer reactor is suddenly decreased, the temperature in the reformer reactor is rapidly increased, thereby damaging the construction materials thereof. In order to solve this problem, a controlling system for the reforming reaction transitionally reduces the pressure in the reformer reactor when the sudden decrease of load takes place, so as to increase the reaction rate in said reformer reactor, and to increasing the quantity of endothermic heat by said reaction, thereby controlling the rapid increase of temperature in the reformer reactor.
