MAFC verses HFC (Hydrogen Fuel Cell)

• MAFC is less expensive than HFC
• MAFC technology is less complex
• MAFC requires fewer components
• MAFC requires no specialized manufacturing, HFC manufacturing is specialized
• Magnesium is less volatile/combustible than hydrogen
• No special fuel storage needed for magnesium, while hydrogen requires special storage container
• Fuel for MAFC can either be magnesium or magnesium-alloy, while fuel (hydrogen) for HFC
  must be of relative high purity
• Magnesium is more readily obtainable than hydrogen for the portable consumer products
• MAFC electrolyte (salt water, sea water) is more environmentally friendly and less expensive than that for HFC
• MAFC is easily transportable via plane (no special permit needed), HFC may need a permit but hydrogen will certainly need a special permit
• MAFC is easily recycled
• MAFC is very consumer friendly 
• MAFC is more energy efficient per cell than HFC (90% vs 45% – 60%)
• MAFC voltage is higher per cell than HFC (1.8 vs 0.8V)
• MAFC operating temp is lower than HFC (55C vs 70-100C)
• MAFC can operate at low temperatures (-20C), HFC does not operate very well at low temperatures
• MAFC has indefinite storage life
