Abstract
An electrode material of a fibrous structure has a platinum-based electrocatalytic material, an electrospinning polymer material, and an oxide material and/or one or more organophosphorus acid material with ion conduction. In the micromorphology has the structure of nanofibers, but also has porous morphological characteristics, the electrode material of this structure is prepared by electrostatic spinning technology, can be used as a high-temperature polymer electrolyte membrane fuel cell porous electrode.
Claims7
A fibrous electrode material, comprising:
- an active electrocatalytic material, polymer fibers, an oxide material, and an organophosphorus acid,
- wherein the polymer fibers are interwoven to form a carrier, the oxide material is affixed to the carrier and forms a porous structure, and the organophosphorus acid is affixed to the carrier, and
