Abstract
A water electrolysis apparatus is formed by stacking a plurality of unit cells. Each unit cell includes a membrane electrode assembly, and an anode separator and a cathode separator which sandwich the membrane electrode assembly therebetween. The anode separator has a plurality of inlet joint channels in fluid communication with a water supply passage, and a plurality of outlet joint channels in fluid communication with a discharge passage. The water supply passage has an inner wall surface at which the inlet joint channels are open, and an outer wall surface which faces the inner wall surface, the inner wall surface and the outer wall surface jointly forming an opening of an oblong cross-sectional shape.
