Abstract

Un sensor de gas formado como celda electroquímica que tiene una pequeña cantidad de componentes y que es de fabricacion economica y que comprende electrodos (22, 24) formados como elementos planos porosos en un substrato (20), donde el substrato es poroso para permitir que el gas permee hacia los electrodos desde el exterior del sensor de gas, terminales de electrodos externos (10) montados en la periferia de un compartimiento (4), donde en la region donde termina la terminal, los electrodos, el substrato y el compartimiento están sujetos a una operacion de soldadura por calor y presion con el fin de mantener las terminales y los electrodos en conexion eléctrica entre sí, en tanto que se impida la porosidad de los electrodos con el fin de evitar que el electrolito permee a través de los electrodos y hacia la conexion eléctrica.
