It was 10 degrees. When this unfired film was used in a Buttonya air zinc battery (two-sided), cracks appeared during discharge, which caused the electrolyte to leak, making it impossible to achieve the specified discharge capacity. The reason why the membrane cracks is because the zinc in the negative electrode is discharged; it reacts with oxygen in the air and expands to form zinc oxide, pushing the gas diffusion electrode and deforming it, causing the membrane to receive tension. In addition, some batteries used porous fluororesin membranes that were fired entirely to strengthen the ! If the bonding properties are poor and the pressure bond is weak, the dissolution liquid may accumulate between the unfired fluororesin membrane and the unfired fluororesin membrane during release or storage, which prevents the supply of the element in the air to the catalyst 71. In addition, the reason why the adhesion of the fired membrane to the catalyst layer 1 is weak is because it has less elongation than the unfired membrane (2). Due to the low elongation, the unevenness of the surface of the catalyst layer cannot be absorbed, resulting in weaker adhesion.Increasing the pressure to strengthen the adhesion will crush the small pores at the waist (two), impairing air permeation. However, there was a problem that the required amount of oxygen could not be supplied.

、電解液の漏液もない。[For 1] As mentioned above, in the present invention, the unfired surface of the fluororesin film is bonded to the catalyst layer (= bonding), so the surface of the catalyst layer has fine irregularities (= the surface of the membrane is intruded, due to the wedge effect). Such a gas diffusion magnetic pole can obtain a sufficient supply of oxygen, and since no cracks occur in the membrane, there is no leakage of electrolyte.
