Title
(ES) UNION DE COMPONENTES DE CELDAS ELECTROQUIMICAS.
Abstract
(ES)
Un método para preparar una placa bipolar para una celda electroquímica, que comprende: alinear un premontaje que tiene una placa y un campo de flujo, con uno o más elementos de unión dispuestos entre ellos, en el que los elementos de unión tienen una temperatura de punto de fusión que es menor que la temperatura de punto de fusión de los componentes de la placa y el campo de flujo, comprimir el premontaje, calentar el premontaje a una temperatura menor que 800ºC y permitir que el premontaje se enfríe.
