Abstract

LA PRESENTE INVENTION CONCERNE UN PROCEDE POUR REDUIRE LA TENSION DE SORTIE DES PILES A COMBUSTIBLE. ON REDUIT LE RENDEMENT DES PILES A COMBUSTIBLE EN RECYCLANT UNE PARTIE DU COURANT DE REACTIFS A LA SORTIE DE LA CATHODE AU TRAVERS DES PILES ET, SI NECESSAIRE, EN REDUISANT EGALEMENT LE DEBIT D'AIR TOTAL VERS LES PILES DANS LE BUT DE PERMETTRE UN FONCTIONNEMENT A UN NIVEAU DE TENSION INFERIEUR A CELUI QUI SERAIT AUTREMENT PRODUIT AVEC UNE TENSION EXCESSIVE. L'INVENTION EST PAR EXEMPLE UTILISABLE DANS DES INSTALLATIONS DE PRODUCTION D'ENERGIE EN PILES A COMBUSTIBLE.
