10 Fuel Cells Capable of Operating in Ultra-High-Temperature Environments 

2 Solid Electrolyte Most Ideal for Fuel Cells Operating at Higher Temperatures (600-1,000°C) 

Two distinct electrolytes, namely molten electrolyte and solid electrolyte, have been investigated for high-power sources. A fuel cell using molten electrolyte, hydrogen fuel, and air as oxidant that produced a power density of 45 W/ft. at 0.7 V has demonstrated a remarkable reliability. A two-cell device demonstrated a power density of 58 W/ft. at 1.3 V and a continuous operation exceeding 4,000 h with no deterioration in cell performance.
