Abstract

L'invention concerne un procédé de surveillance du bon fonctionnement des cellules d'une pile à combustible, la pile à combustible étant constituée d'un ou de plusieurs empilements de cellules élémentaires reliées en série les unes aux autres, lesdits empilements étant reliés entre eux en série et/ou en parallèle par des raccordements électriques. Ce procédé comprend les étapes consistant à :- dans chaque empilement de cellules élémentaires, considérer deux parties (partie A et partie B) comprenant un même nombre de cellules élémentaires et étant disposées de manière symétrique dans l'empilement des cellules élémentaires par rapport au milieu dudit empilement,- pour chaque empilement,- mesurer les tensions des deux parties A et B,- comparer ces deux mesures.The invention relates to a method for monitoring the proper functioning of the cells of a fuel cell, the fuel cell consisting of one or more stacks of elementary cells connected in series with each other, said stacks being connected to each other in series and / or in parallel by electrical connections. This process includes the steps of: - in each stack of elementary cells, consider two parts (part A and part B) comprising the same number of elementary cells and being arranged symmetrically in the stack of elementary cells with respect to the medium of said stack, - for each stack, - measure the voltages of the two parts A and B, - compare these two measurements.
