Abstract

"CéLULA ELETROQUìMICA POSSUINDO UMA SEGURANçA APERFEIçOADA". é proporcionada uma célula onde fora dos padrões convencionais dos eletrodos constituindo a célula, os dois eletrodos mais externos são ambos cátodos, os coletores de corrente do cátodo dos cátodos são revestidos em um único lado com materiais de cátodo ativos nas primeiras superfícies dos mesmos, outros lados dos coletores de corrente do cátodo não revestidos com materiais de cátodo ativos são dispostos em direção o lado de fora da montagem de célula e a espessura dos coletores de corrente do cátodo é 70 à 150% desta da camada revestida com material de cátodo ativo. A célula de acordo com a presente invenção exibe excelente segurança em uma teste de penetração de prego.
