ABSTRACT:
A fuel cell generation system comprises a cell stack consisting of a plurality of cells, said cell having a fuel electrode, an oxidizer electrode, and an electrolyte layer located between said both electrodes, a fuel cell main body having a plurality of cooling plates for absorbing heat generated in said cell, said plate being located between said cells, and a cooling unit for supplying a coolant through said cooling plate. The system further provides a reference voltage source for supplying a reference voltage and a determining unit for comparing an output voltage of at least one cell located at the upper portion of the cell main body with the reference voltage and determining if an abnormal state occurs in the cooling unit based on the comparing result. The reference voltage is picked up out of a part of the cell stack.
