CATALYST LAYER CONSTITUTING BODY AND METHOD FOR PREPARING CATALYST LAYER CONSTITUTING BODY

Document Type and Number:

WIPO Patent Application WO/2013/114957

Kind Code:

A1

Abstract:

Provided is a catalyst layer constituting body in which runoff of a proton-conducting polymer from a catalyst layer can be prevented, even when water is generated by the operation of a fuel cell. A catalyst layer constituting body of a fuel cell in which catalyst particles are carried by carbon, wherein: the catalyst particles are carried on the carbon with a carrying layer, comprising an upper and a lower layer, interposed therebetween; the upper layer of the carrying layer is a proton-conducting layer formed from a proton-conducting polymer, the proton-conducting layer conducting protons generated in the catalyst particles and protons to be supplied to the catalyst particles; and the lower layer of the carrying layer is a bonding layer formed from a polymer having an affinity with both the proton-conducting layer and the carbon, the bonding layer bonding the proton-conducting layer and the carbon to each other.
