A fuel cell is provided which can control an optimum fuel concentration according to an output without a sensor for measuring the fuel concentration. The fuel cell uses a liquid organic compound for fuel and includes a membrane-electrode assembly, a passage for allowing fuel or oxidant to flow, a fuel supply unit for supplying the fuel to the fuel cell and intermittently or periodically changing a rate of fuel supply, and a computation processor for measuring a signal of a voltage or an output of the fuel cell, computing the rate of the fuel supply and the signal, and correcting the rate of the fuel supply. In the fuel cell, the optimum fuel concentration can be easily controlled according to the output by periodically varying the fuel concentration from a reference fuel concentration, measuring a voltage or an output and a variation range of the voltage or the output, and then determining whether the reference fuel concentration is appropriate or not.

A polymer electrolyte fuel cell comprising a first separators for oxidizing gas and a second separator for fuel gas and a membrane/electrode assembly sandwiched between the separators. A first group of oxidizing gas flow passages flowing, from an entrance towards a turning point, has the longer length than a second group of oxidizing gas flow passages. The second group of flow passages, from the turning point towards an exit, are formed on the plane of the first separator. A downstream of the flow passages of the first group is located near an upper stream of the flow passages of the second. The flow passages of the first group and flow passages of the second group adjoin one another on the plane of the first separator.
