Abstract

A catalyst layer material, a method for fabricating the same, and a fuel cell are provided. The catalyst layer material utilized for the fuel cell includes a catalyst support and a catalyst distributed on the catalyst support. The catalyst support contains Ti x M 1−x O 2 , wherein M is selected from the group consisting of a Group IB metal, a Group IIA metal, a Group IIB metal, a Group IIIA, a Group VB metal, a Group VIB metal, a Group VIIB metal and a Group VIIIB metal, and 0<X≦0.9. By applying the non-carbonaceous catalyst support containing high conductivity metal elements to the fuel cell, stability and performance of the cell can be effectively enhanced.

First claim

What is claimed is:

1. A catalyst layer material for a fuel cell, the catalyst layer material comprising:
a catalyst support comprising Ti x M 1−x O 2 , wherein M is selected from the group consisting of a Group IIA metal, a Group VIIB metal and a Group VIIIB metal, and 0<X≦0.9, the Group IIA metal is Sr, the Group VIIB metal is selected from the group consisting of Mn, Tc and Re, and the Group VIIIB metal is selected from the group consisting of Fe, Co and Ni; and
a catalyst, distributed on the catalyst support.

2. The catalyst layer material according to claim 1 , wherein 0.5≦X≦0.9.

3. The catalyst layer material according to claim 1 , wherein the catalyst comprises Pt or Pt alloys.

4. A fuel cell, comprising:
a first gas diffusion layer and a second gas diffusion layer;
a first catalyst layer and a second catalyst layer both disposed between the first gas diffusion layer and the second gas diffusion layer, wherein at least one of the first catalyst layer and the second catalyst layer comprises the catalyst layer material according to claim 1 ; and
a polymer film, disposed between the first catalyst layer and the second catalyst layer.
