Title
(EN) REACTANT GAS SUPPLY FOR FUEL CELLS OR ELECTROLYSIS CELLS
(FR) ALIMENTATION EN GAZ RÉACTIF POUR PILES À COMBUSTIBLE OU CELLULES D'ÉLECTROLYSE
Abstract
(EN)
A fuel cell, electrolysis cell or a fuel cell stack or an electrolysis cell stack comprising a plurality of planar fuel cells or electrolysis cells has alternating flow direction of the cathode gas, the anode gas or both leading to a mixture of un-used gas and partly used gas and equalization of the temperature profile of the fuel cell(s) or electrolysis cell(s).
(FR)
L'invention porte sur une pile à combustible, une cellule d'électrolyse ou un empilement de piles à combustible ou un empilement de cellules d'électrolyse comprenant une pluralité de piles à combustible ou de cellules d'électrolyse planes, ayant un sens d'écoulement alternatif du gaz de cathode, du gaz d'anode ou des deux, entraînant un mélange de gaz non utilisé et de gaz partiellement utilisé et une égalisation du profil de température de la ou des piles à combustible ou de la ou des cellules d'électrolyse.
