燃料電池スタック用双極極板 - SGL Carbon Actien Gezershaft

Title:

燃料電池スタック用双極極板

Document Type and Number:

Japanese Patent JP4383710

Kind Code:

B2

Abstract:

Bipolar plates (516) for electrochemical cells, particularly low-temperature fuel cells, with surface modification to enhance through-plate conductivity, processes for improving the surface properties of those bipolar plates, and fuel cell assemblies made with such plates. Graphite-polymer composite bipolar plates with high bulk conductivity are subjected to an abrasive surface treatment to improve the surface contact as well as the reactant transfer to the adjacent gas diffusion electrodes.
