Asahi Glass Co., Ltd. has developed a fluorine-based electrolyte polymer for fuel cells that is thinner and more flexible, and has a durability that is more than five times that of the original electrolyte membrane.
When a fuel cell generates electricity, water is generated in the battery cell, and the electrolyte membrane swells and swells. When the power generation stops, it shrinks and shrinks. This process is repeated, causing complicated mechanical stress to be applied to the electrolyte membrane, eventually causing it to rupture and failing to play again. The function of the diaphragm.
Asahi Glass researched the chemical structure of the polymer and developed a new type of electrolyte polymer with better toughness, which can reduce and disperse mechanical stress, and maintain the three-dimensional microstructure even after repeated deformation, which is not easy to deteriorate. The thickness is reduced to 5 microns, but it still shows the durability of the dry and wet cycle of the original electrolyte membrane more than 5 times, which successfully breaks the relationship between the thin film and the durability of the dry and wet cycle.
