FuelCell Energy Engine Fluids
FCEV (Fuel Cell Electric Vehicle)*: FCEVs use a propulsion system similar to electric vehicles, where energy is stored as hydrogen converted to electricity by the fuel cell.
|Similar to conventional internal combustion engine vehicles, they can fuel in less than 10 minutes and have a driving range of around 300 miles. The most common type of fuel cell for vehicle applications is the polymer electrolyte membrane (PEM) fuel cell. In a PEM fuel cell, an electrolyte membrane is sandwiched between a positive electrode (cathode) and a negative electrode (anode). Hydrogen is introduced to the anode and oxygen (from air) to the cathode. The hydrogen molecules break apart into protons and electrons because of an electrochemical reaction in the fuel cell catalyst. Protons travel through the membrane to the cathode. The electrons are forced to travel through an external circuit to perform work (providing power to the electric car) then recombine with the protons on the cathode side, where the protons, electrons, and oxygen molecules combine to form water.|
***->Unique feature of cooling system of FCEV is that it contains Ion exchange resin. To avoid the absorption of contamination or additive package in cooling circuits by the Ion exchange resin, the coolant must have low electronic conductivity.
