Compare Fuel Cell and Combustion

• Energy Efficiency of Fuel cells

  • Have higher energy efficiencies compared to combustion processes. Convert chemical energy directly into electrical energy
• Energy of Efficiency of Combustion processes

  • Have lower energy efficiencies compared to fuel cells
  • Involve the conversion of chemical energy into heat energy
• Safety of Fuel cells

  • Are safer than combustion processes because they operate at lower temperatures and do not involve combustion reactions
• Safety of Combustion

  • Involve the rapid oxidation of fuel with oxygen, often resulting in the generation of high temperatures and potentially harmful emissions
• Fuel supply of Fuel cells

  • Use hydrogen as a fuel, which can be produced from a variety of sources, including natural gas, biomass, and electrolysis of water
  • The storage of hydrogen is dangerous which requires specialised equipment
• Fuel supply of Combustion processes

  • Can employ a wide range of fuels, including fossil fuels and renewable fuels
  • These fuels are easier to store and transport compared to hydrogen
• Production of greenhouse gases from Fuel Cell

  Fuel cells only require H2 and O2, don't produce waste (CO2) and environmental impacts
• Production of Greenhouse gases for Combustion

  Combustion of fuel produces carbon dioxide (CO2), affect the greenhouse gases, contributing to global warming and air pollution
