Original Abstract Submitted

a water electrolysis cell includes an electrolyte membrane that is sandwiched between two catalyst layers, the two catalyst layers, two microporous layers each of which is disposed adjacent to a surface of each of the catalyst layers opposite to the electrolyte membrane side, two gas diffusion layers each of which is disposed adjacent to a surface of each of the microporous layers opposite to the catalyst layer side, and two separators each of which is disposed adjacent to a surface of each of the gas diffusion layers opposite to the microporous layer side. in the water electrolysis cell, an area of one of an oxygen electrode and a hydrogen electrode is smaller than an area of the other, and adhesion strength between each of the microporous layers and each of the catalyst layers is higher than that between each of the gas diffusion layers and each of the microporous layers.
