Abstract

Electrodo, en especial para células de combustible, con poros para el paso de un fluido, en especial gas, que penetran desde una superficie (1) del lado del gas hasta una superficie (2) del lado del electrólito, y con por lo menos un punto de contacto (3) que es conductor de electrones, caracterizado porque el electrodo tiene por lo menos un conductor colector (4), cuya resistencia específica es menor que la resistencia específica del electrodo.
