Working conditions of perfluorosulfonic acid proton exchange membrane Water transport in proton exchange membrane fuel cells involves two aspects, one is the drag of proton water from the anode to the cathode by electroosmosis, and the other is the diffusion in the opposite direction. The total flux of water transport is the sum of electroosmotic drag and reverse diffusion. The water balance of the proton exchange membrane belongs [...]

Spray-Coated Perovskite Solar Cells Spray-Coated Perovskite Solar Cells - Ultrasonic Coating - Cheersonic Perovskites have many properties that make them popular materials for solar cell applications.
