Title:
ELECTRODE CATALYST LAYER, MEMBRANE ELECTRODE ASSEMBLY, AND SOLID POLYMER FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2022/124407
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an electrode catalyst layer, a membrane electrode assembly, and a solid polymer fuel cell, which are capable of improving material transport properties and proton conductivity in the electrode catalyst layer, and which are capable of exhibiting high power generation performance over the long term and have good durability. An electrode catalyst layer (10) is an electrode catalyst layer used in a solid polymer fuel cell, and includes: a catalyst material (12); a conductive carrier (13) that supports the catalyst material (12); a polymer electrolyte (14); and a fibrous material (15), wherein the fibrous material (15) contains a substance having a nitrogen atom, and is included in an amount of 1-12 wt% (exclusive of 12) in the electrode catalyst layer (10).
