<P>PROBLEM TO BE SOLVED: To provide a fuel cell system with control means dispersed, having improved safety when a failure occurs in communicating the control means with each other, and an improved versatility in assigning an auxiliary machine to the control means. <P>SOLUTION: The fuel cell system comprises a main control means for controlling a series of operations of a fuel cell, represented by the start, power generation and stop of the fuel cell system, a sub control means for performing axiliary machine control determined by the control of the main control means, a fan and a pump for feeding air and water to be controlled by the control means including the main control means and the sub control means, and valves for changing over flow paths for gas, air and water. When a failure occurs in communicating the main control means and the sub control means with each other, the main control means and the sub control means independently perform stopping processing for the fuel cell. Thus, even when the failure occurs in communicating the control means with each other, the auxiliary machine connected to the sub control means can be controlled by the sub control means to stop the fuel cell. This improves the safety of the fuel cell when the communicating failure occurs. <P>COPYRIGHT: (C)2010,JPO&INPIT |
