Protonic Ceramic Fuel Cells
Protonic Ceramic Fuel Cells
protonic ceramic fuel cells (PCFCs) incorporate a proton-conducting oxide as the electrolyte material. Like other fuel cells, they enable direct electrochemical conversion of chemical fuels to electricity at high efficiency and with zero emissions. They are particularly attractive in comparison to other fuel cells as a consequence of the high ionic conductivity of the electrolyte at intermediate temperatures (400–600 °C). It is widely recognized that high-power operation in this temperature regime is key to lowering fuel cell costs. A further challenge in PCFC development lies in the reactivity of many protonic ceramic electrolytes with CO2, precluding their use at intermediate temperatures with carbon containing fuels.
