Abstract
Official abstract text for this publication.
An electrode for use in a fuel cell comprises a flexible carbon-fiber nonwoven fabric and a fuel cell catalyst, such as a metal catalyst or a carbon alloy catalyst, supported on the surfaces of the carbon fibers constituting the flexible carbon-fiber nonwoven fabric. The flexible carbon-fiber nonwoven fabric is formed by carbonizing a nonwoven fabric obtained by electrospinning a composition containing: an electrospinnable macromolecular substance; an organic compound that is different from the macromolecular substance; and a transition metal. This structure allows the provision of an electrode, for use in a fuel cell, which uses a flexible carbon-fiber nonwoven fabric as a substrate and combines the functions of a gas-diffusion layer and an electrocatalyst layer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fuel cell electrode having both a gas diffusion function and an electrocatalyst function, consisting of: a flexible carbon fiber nonwoven fabric from a nonwoven fabric electrospun, the nonwoven fabric electrospun comprising a composition containing an electrospinnable polymeric substance, an organic compound as a carbon precursor different from the electrospinnable polymeric substance, and a transition metal; and a fuel cell catalyst supported on s…
