Abstract

"SEMI-ELEMENTO ELETROQUìMICO". A presente invenção refere-se a uma meia célula eletroquímica para preparação de cloro a partir de soluções aquosas de cloreto de álcali apresenta um espaço de eletrodos (17) para conter um eletrólito. Além disso, estão previstos diversos bolsos de gás (26, 27, 28, 29) sendo que os bolsos de gás (26, 27, 28, 29) do espaço de eletrodos (17) estão separados do espaço de eletrodos (17) por um eletrodo de difusão a gás (5). De acordo com a invenção a meia célula apresenta um elemento suportador (2) para suportar os bolsos de gás (26, 27, 28, 29), que se situam na parede posterior (20) aos bolsos de gás (26, 27, 28, 29) em toda a sua superfície, ou formam a parede posterior (20) dos bolsos de gás (26, 27, 28, 29).
