Electrolyzer Cell Voltage to Efficiency Calculator
The default 1.8 V cell gives 47.862 kWh/kg and 82.3% HHV. Convert cell voltage to stack SEC and HHV/LHV efficiency; add balance-of-plant losses for system SEC.
Enter cell voltage to calculate stack-level kWh/kg, HHV efficiency, LHV efficiency, and the thermoneutral voltage. Add balance-of-plant losses before using a system SEC. Compare the result on HHV/LHV bases with the efficiency converter.
Convert cell voltage into stack-level specific energy and efficiency while keeping thermoneutral voltage visible. Add auxiliary losses for a system figure.
