New PBI/H3PO4 Fuel Cell Starts Up at Room Temperature

The acid-base composite electrolyte membrane using PBI or other basic polymers: The acid-base interaction is caused by doping phosphoric or other acid so that the acid is immobilized in the polymer chain. The bond created by immobilization is not strong but rather fluid. Phosphoric acid migrates to the air electrode with protons.
