Abstract

"ARTIGO DE GRAFITE FLEXìVEL E ELETRODO PARA CéLULA DE COMBUSTìVEL COM CONDUTIVIDADES ELéTRICA E TéRMICA INTENSIFICADAS". Apresenta-se um artigo de grafite (20) útil para produzir um conjunto (6) de membrana e eletrodos, compreendendo um par de eletrodos e uma membrana trocadora de íons (550) posicionada entre os eletrodos. Pelo menos um dos eletrodos é constituído de uma lâmina de massa comprimida de partículas de grafite expandidas, tendo uma pluralidade de canais transversais de fluido (20) que passam através da lâmina entre a primeira e a segunda superfícies opostas da lâmina, uma das superfícies opostas encostando na membrana trocadora de íons (550) quando usada em um conjunto (6) de membrana e eletrodos. Pelo menos alguns dos canais de fluido (20) são interligados, para permitir o escoamento do fluido entre eles."FLEXIBLE AND ELECTRODE GRAPHITE ARTICLE FOR FUEL CELL WITH INTENSIFIED ELECTRIC AND THERMAL CONDUCTIVITY". A graphite article 20 useful for producing a membrane and electrode assembly 6 is provided, comprising a pair of electrodes and an ion exchange membrane (550) positioned between the electrodes. At least one of the electrodes is comprised of an expanded graphite particle compressed mass sheet having a plurality of transverse fluid channels (20) passing through the blade between the first and second opposing surfaces of the blade, one of the opposite surfaces. abutting the ion exchange membrane (550) when used on a membrane and electrode assembly (6). At least some of the fluid channels (20) are interconnected to allow fluid flow between them.
