摘要： A method for producing a catalyst-supporting support made up of catalyst-supporting carbon and an electrolyte polymer is provided which is characterized by including: a step of allowing carbon with pores to support a catalyst; a step of introducing a functional group, which is to be a polymerization initiator, into the surface and/or the pores of the catalyst-supporting carbon; and a step of introducing an electrolyte monomer or electrolyte monomer precursor into the surface and/or the pores of the catalyst-supporting carbon to polymerize the introduced electrolyte monomer or electrolyte monomer precursor using the polymerization initiator as a polymerization initiation site, whereby a three-phase boundary at which the reaction gas, catalyst and electrolyte meet can be sufficiently ensured in the carbon, and thus the catalyst can be more efficiently utilized. The use of the catalyst-supporting support enables electrode reactions to progress efficiently and the efficiency of power generation of a fuel cell to be increased. Further, the use of the catalyst-supporting support makes it possible to provide an electrode having excellent characteristics and a polymer electrolyte fuel cell including the electrode with which high output can be obtained.

摘要： A method of estimating a deteriorated state of a battery mounted on a vehicle includes first to third steps. The first step is a step of obtaining a voltage value and a current value of the battery a plurality of times during a data acquisition period and storing the values in a memory. The second step is a step of subjecting the voltage value and the current value during the data acquisition period stored in the memory to Fourier transform and calculating an impedance component for each frequency band based on the voltage value and the current value subjected to Fourier transform. The third step is a step of estimating high-rate deterioration of the battery by comparing a ratio E between a medium-frequency impedance ZM and a low-frequency impedance ZL2 with a reference value K.
