Abstract

ESTRUTURA DE ELETRODO DE RESISTêNCIA VARIáVEL. Trata-se de uma estrutura de eletrodo em um dispositivo de célula de combustível que inclui um elemento de transferência de carga (112, 212, 612, 712). Um elemento eletricamente condutor (605) inclui um coletor de corrente (222, 226) disposto no elemento de transferência de carga, no qual o conector está estruturado na forma de um padrão de recorte não uniforme expondo o elemento de transferência de carga e tendo uma resistência não uniforme para otimizar a conexão de corrente.
