Abstract

reator eletroquímico bipolar de múltiplas células com interligações elétricas bipolares planas e dutos internos de circulação de soluções de eletrólito através de todos os respectivos compartimentos de células. a presente invenção refere-se a uma arquitetura de pilha de células bipolares sem armação com coletores internos de circulação de soluções de eletrólito "em paralelo" através de todos os respectivos compartimentos de células ou dutos internos configurados para permitir caminhos de fluxo "seriais"das soluções de eletrólito em sucessão através de todos os respectivos compartimentos de células da pilha, não emprega qualquer armação de plástico e emprega interligados elétricas bipolares substancialmente planas (i) de condutividade elétrica substancialmente homogênea com um perimetro que se sobrepõe ao perímetro de qualquer outro elemento da pilha. sempre que útil para aplicação particular, as interligações planas podem ter uma "parte de alça" protuberante que se projeta além do lado de perímetro externo dos outros elementos empilhados, fornecendo uma área contantável externamente suficientemente grande para a energia (classificação de corrente) de uma derivação elétrica, em uma tensão intermediária em relação à diferença de tensão entre os terminais de extremidade da pilha, conectáveis a um circuito externo. a arquitetura de pilha sem armação emprega montagens de membranas permiônicas (m) compreendendo duas gaxetas de elastômero idênticas (g1, g2) que definem uma abertura ou janela central fechada pela membrana (m) que tem partes de bordas de perímetros retidas de modo vedado entre superfícies de vedação essencialmente planas do "lado traseiro" das duas gaxetas idênticas dispostas costa com costa. o "lado dianteiro" das gaxetas tem uma área de vedação de perímetro modelada em baixo relevo que tem laços que contornam completamente os furos passantes (1+2,3+4) a ser vedados do compartimento de fluxo, deixando em comunicação com o compartimento de fluxo outros furos passantes (4+3,2+1), de entrada e saída da respectativa solução de eletrólito. cada montagem de membrana é comprimida eventualmente entre duas interligações elétricas planas ao apertar os elementos empilhados conjuntamente, preferivelmente interpondo espaçadores perimetrais (9) para impedir compressão não uniforme ou excessiva dos recurso modelados em baixo relevo e manter as interligações planas paralelas umas às outras.
