Title:
FUEL CELL ELECTRODE USING POROUS GRAPHITE FILM, FILM- ELECTRODE BONDED BODY AND FUEL CELL
Document Type and Number:
Japanese Patent JP2003317729
Kind Code:
A
Abstract:

To obtain a fuel cell electrode having a carrier structure capable of effectively utilizing a noble metal based catalyst, capable of surely securing an exhaust passage for fuel gas, an electron, a proton and water, and in addition capable of maintaining a stable performance for a long period of time, a film- electrode bonded body and a fuel cell, by a simple manufacturing process.

This fuel cell electrode has a structure wherein an alloy particulate containing a noble metal or a noble metal element is carried on the inner wall of the very fine hole of a porous graphite film having a very fine communicating hole, and the inner wall of the communicating hole of the electrode is coated with an electrolyte material to conduct an ion. The fuel cell electrode is bonded on at least one side of the electrolyte material to conduct the ion to form this film-electrode bonded body (sometimes written as MEA for short). In addition, this fuel cell has the film-electrode bonded body as a component.
