Abstract
Dispositif comprenant un ensemble d'électrodes comportant une cathode et une anode qui sont isolées l'une de l'autre, et une membrane d'électrode qui est supportée par un organe de support et agencée de façon qu'un électrolyte soit placé entre la membrane d'électrode et la partie d'extrémité de l'ensemble d'électrodes. La partie d'extrémité de l'ensemble d'électrodes, surtout l'extrémité de la cathode 1, est en contact très proche de la membrane d'électrode 5, et la membrane d'électrode 5 n'est pas étirée excessivement. En d'autres termes, l'épaisseur de la membrane d'électrode peut être maintenue pratiquement uniforme. En conséquence, on peut obtenir une perméabilité en oxygène stable et une réaction d'électrode stable Application aux instruments médicaux.
