Abstract

"MEIA-PILHA ELETROQUìMICA". A presente invenção refere-se a uma meia-pilha eletroquímica, em particular para a eletrólise de soluções aquosas de cloreto de hidrogênio, pelo menos compreendendo uma área de gás, a área de gás tendo uma alimentação de gás e uma descarga de gás assim como uma saída de líquido, e um eletrodo de difusão de gás que repousa sobre um distribuidor de corrente eletricamente condutivo e faz o contato eletricamente condutivo com o distribuidor de corrente, o distribuidor de corrente tendo uma área livre na faixa de 5 a 65%, preferivelmente de 10 a 60%, particularmente preferível de 15 a 50%, com base na área total do distribuidor de corrente, e uma espessura de 0,3 mm a 5 mm, preferivelmente de 0,35 a 0,6 mm.
