Abstract

La invención se refiere a una pila de celdas de combustible con celdas de combustible apiladas en una dirección de apilamiento (z), cada una de las cuales está diseñada para tener forma de placa, se extiende en una primera y una segunda dirección lateral (x, y) cuando se observa ortogonalmente a la dirección de apilamiento (z), y en la dirección de apilamiento (z), tiene: una media placa bipolar del lado del ánodo con una estructura de canal de combustible para conducir un combustible; una capa de difusión de gas del lado del ánodo; una unidad membrana-electrodo que tiene una membrana electrolítica y capas de electrodos dispuestas a ambos lados de la misma, que forman un ánodo y un cátodo para una reacción electroquímica del combustible con un agente oxidante; una capa de difusión de gas del lado del cátodo; una media placa bipolar del lado del cátodo con una estructura de canal de agente oxidante para conducir el agente oxidante; y placas terminales en ambos extremos de la pila en la dirección de apilamiento z. Según la invención, las zonas de recepción de las correas están fijadas a las placas de los extremos lateralmente a la pila, y las correas se fijan a través de las zonas de recepción de las correas de manera que la pila queda reforzada por las correas.
