Abstract

"PLACAS BIPOLARES DE MONTAGEM". Métodos são proporcionados para a fabricação de artigos de grafite bipolar (110) . Primeiro e segundo componentes (112,114) são formados de material de grafite flexível. O primeiro componente (112) pode ter uma protuberância (122) formada sobre ele, e o segundo componente (114) pode ter um recesso (128) formado nele que é complementar à protuberância (122) do primeiro componente (112). Os primeiro e segundo componentes (112,114) são montados de modo que a protuberância (122) do primeiro componente (112) é recebida no recesso (128) do segundo componente (114) . De preferência, os componentes são feitos de material de grafite impregnado com resina não curada. Os componentes montados são então pressionados juntos e aquecidos para curar a resina de modo a unir os componentes. Alternativamente o segundo componente (114), ou ambos os componentes, pode ter superfícies planas que engatam o outro componente.
