Beschreibung
Zusammenfassung:	An electrolyzer or unitized regenerative fuel cell has a flow field comprising at least one channel, wherein the cross-sectional area of the channel varies along at least a portion of the channel length. In some embodiments the channel width decreases along at least a portion of the length of the channel according to a natural exponential function. The use of this type of improved flow field channel can improve performance and efficiency of operation of the electrolyzer device. L'invention concerne un électrolyseur ou une pile à combustible régénératrice, divisée en unités, comportant un champ d'écoulement contenant au moins un canal. La section transversale du canal varie le long d'au moins une partie de sa longueur. Selon certains modes de réalisation, la largeur du canal diminue le long d'au moins une partie de sa longueur selon une fonction exponentielle naturelle. L'utilisation de ce type amélioré de canal de champ d'écoulement permet d'améliorer le rendement et l'efficacité de l'électrolyseur.
