Abstract
The invention relates to a fuel cell membrane electrode structure with foaming type base materials, comprising a pair of porous electrodes and a proton exchange membrane. Each porous electrode is provided with multiple pores, polymer combined by metal catalyst and carbon particles is adhered in the pores, and the proton exchange membrane is arranged between the porous electrodes. When the fuel cell membrane electrode structure with foaming type base materials is in use, the porous electrodes are made of foaming conduction metal materials so as to help support the structure of the fuel cell. The polymer adhered to the pores of the porous electrodes is metal catalyst which does not contain platinum, so that the manufacturing cost of the fuel cell can be reduced.
Description
technical field [0001] The invention relates to a fuel cell membrane electrode structure with a foamed substrate, in particular to a fuel cell membrane electrode structure with a foamed substrate applied to a proton exchange membrane fuel cell. Background technique [0002] Fuel cells using hydrogen as fuel, the power generation principle is to directly convert chemical energy into electrical energy, so it has the advantages of zero pollution, high electrical energy conversion efficiency, low noise and renewable. The membrane electrode group is the core component of the fuel cell, so the power generation efficiency of the fuel cell can be improved by improving the structure of the membrane electrode group and using a suitable catalyst. [0003] As disclosed in U.S. Patent No. 5,863,673 "Porous Electrode Substrate for Fuel Cells", a fuel cell unit includes: a pair of conductive plates; a membrane electrode group, which is arranged in the middle of the conductive plates, and t...
