Abstract

"GERADOR ELETROQUìMICO". A invenção refere-se a um novo desenho de pilha de células a combustível a membrana ionomérica compreendendo uma multiplicidade de placas bipolares em aço, eletrodos, membranas e vedações perimétrica de selagem reclusas entre placas de compressão. O desenho é dirigido a prevenir o aumento de íons metálicos nas membranas e o consequente declínio das tensões; para esta finalidade, é impedida a migração lateral dentro das membranas ionoméricas dos íons metálicos contidos no fluido de resfriamento.
