Cells producing electricity continuously from fuel supply
Need external fuel supply, not internal storage
Hydrogen-oxygen fuel cell
2H2+O2→2H2O2H_2 + O_2 \rightarrow 2H_2O2H2+O2→2H2O
H2→2H++2e−H_2 \rightarrow 2H^+ + 2e^-H2→2H++2e−
O2+4H++4e−→2H2OO_2 + 4H^+ + 4e^- \rightarrow 2H_2OO2+4H++4e−→2H2O
Anode to cathode via external circuit
Water only
Only produce water (non-polluting)
Less waste than non-rechargeable batteries
Highly flammable gas
Takes more space than liquid/solid fuels
Expensive and complex to develop
Space Shuttle & International Space Station
Efficient with low environmental impact
