    摘要: A fuel cell system includes a cathode, an anode, a fuel supply unit configured to supply a fuel containing methanol and water to the anode, a methanol supply unit configured to supply methanol to the fuel, a sensor which measures a methanol concentration of the fuel, a current measuring unit configured to measure a current flowing between the cathode and the anode, a concentration adjusting unit and a correction unit. The concentration adjusting unit is configured to adjust the methanol concentration of the fuel by controlling the methanol supply unit by using an output value of the sensor. The correction unit is configured to correct a data of a relation between the methanol concentration of the fuel and the output value of the sensor, using an output of the current measuring unit.

    摘要: The present invention provides a catalyst having high activity and excellent stability, a process for preparation of the catalyst, a membrane electrode assembly, and a fuel cell. The catalyst of the present invention comprises an electronically conductive support and catalyst fine particles. The catalyst fine particles are supported on the support and are represented by the formula (1): PtuRuxGeyTz (1). In the formula, u, x, y and z mean 30 to 60 atm %, 20 to 50 atm %, 0.5 to 20 atm % and 0.5 to 40 atm %, respectively. When the element represented by T is Al, Si, Ni, W, Mo, V or C, the content of the T-element's atoms connected with oxygen bonds is not more than four times as large as that of the T-element's atoms connected with metal bonds on the basis of X-ray photoelectron spectrum (XPS) analysis. When the T-element is Ti, Hf, Sn, Ta, Zr or Nb, the content of the T-element's atoms connected with metal bonds is not more than twice as large as that of the T-element's atoms connected with oxygen bonds on the basis of XPS analysis.
