Abstract
A liquid fuel direct supply fuel cell system capable of being operated under optimal conditions. A plurality of cells each having an anode and a positive electrode disposed oppositely through an electrolytic film and being fed, respectively, with liquid fuel and oxidizing agent gas are connected in series as a power generating section (), which is then provided with a sensor section () for detecting the concentration of the liquid fuel in association with a temperature detected by a temperature detecting element thus producing a cell stack (), and a controller () controls high concentration fuel supply amount from a high concentration fuel tank () to a fuel tank () based on an output signal from the sensor section ().
