what is a fuel cell?
The operating principle of the fuel cell is based on the oxidation of a fuel (e.g. hydrogen) and the reduction of a comburant (e.g. oxygen) leading to the simultaneous production of water, electrical energy (W) and heat (Q). This consists of two electrodes one emitting electron( anode) and the other receiving electrons (cathode), separated by an electrolyte allowing the passage of ions. A membrane prevents the contact of the anode and cathode reagents.
Different types of fuel cells
Phosphoric Acid fuel cells (PAFC)
Proton Exchange Membrane (PEM)
Solid Oxide fuel cells (SOFC)
Alkaline fuel cells
Advantages & disadvantage of Fuel cells
- air protection.
- limitation of the noise nuisance: no noise affected by the process of the electrochemical.
- fuel flexibility.
- quick response to the charge and autonomy.
- limited maintenance
- these are batteries = no charging contrary to the batteries.
- New technology.
- Unavailability of hydrogen.
- H2 storage difficulties and risk of explosion.
- Forced by temperatures.
- Lack of infrastructure.
