Compare Fuel anf Galvanic

• Galvanic cell definition:

  Non-rechargeable and involves a conversion of chemical energy from spontaneous redox reaction to electrical energy
• Fuel Cell definition :

  Non-rechargeable and involves a conversion of chemical energy to electrical energy via a redox reaction
• Galvanic Cell function:

  • Set amount of reactants and products
• Fuel Cellfunction:


  • Reactants continuously supplied and products continuously excreted
• Galvanic Cell design feature:

  • Electrodes are not usually porous (use twos half cell with different electrodes)
• Fuel Cell design feature:

  • Electrodes are porous
• Energy Transformation in Galvanic Cell

  Convert chemical energy stored in reactants into electrical energy through spontaneous redox reactions at the electrodes
• Energy Transformation in Fuel Cell

  Convert chemical energy stored in fuel and oxidant directly into electrical energy through electrochemical reactions at the electrodes
• Energy Efficiency of Galvanic Cell

  Less Energy Efficiency compared to Fuel cell as energy loss due to heat excess
• Energy Efficiency of Fuel Cell

  More Energy Efficiency compared to Galvanic Cell
