FUEL CELL

摘要

A gas diffusion electrode for use in a fuel cell assembly off a fuel cell for use with a source of gaseous reductant and a source of gaseous oxidant. The assembly comprises a central ionic membrane having a membrane first surface and a membrane second surface; a first matrix formed of an organic polymer having a first matrix first surface in contact with the membrane first surface and a first matrix second surface; a second matrix formed of an organic polymer having a second matrix first surface in contact with the membrane second surface and a second matrix second surface; a first current collector within the first matrix; a second current collector within the second matrix and in electrical communication with the first current collector; wherein each of the first and the second matrices has a pore structure as to allow of gas permeation within the matrix and water exudation out of the matrix, and contains particulate carbon and wherein at least a portion of each of the first and the second matrices contain catalytic material-coated particulate carbon as to constitute catalytic portion. The fuel cell provides electrochemical and mechanical performance and a stabilized current voltage output under varying load conditions.
