A High Temperature-Stable Derivative of Anhydrous Phosphoric Acid
Hydrogen-oxygen fuel cells require an electrolyte that allows positively charged ions to pass from the anode to the cathode. Phosphoric acid is used in either liquid or membrane forms as an electrolyte and is stable to temperatures of 160°C. Above that temperature the compound breaks down causing loss of conductivity. Higher operating temperatures...
