Driving tomorrow's car with today's manufacturing technologies
Fuel cell is a technology which is starting to stand up as one of the possible firm candidates to drive the future electrical vehicles(EV). The importance and the future possibilities of this generation method is pushing forward in a world where internal combustion engines(ICE) are currently suffering by international laws and available resources
What implies this technology? New breakthroughs comes with new challenges, and the producers are wondering what production resources do they need to feed the demand of the market
First let's go to the basics. What is a fuel cell car ? New models keep being launch to the market such as the Mercedes GLC F-Cell, coexist with more experienced car such as the Toyota Mirai.
These type of cars they use a electrical motor connected to a battery, and the electricity needed to power it, is coming from a Fuel cell.
In an hydrogen fuel cell, the electricity is generated when mollecules of hydrogen and oxygen are mixed together, driving to a result of water (H2O) and energy.
These reaction is happening in the bipolar plates of the fuel cell. But each plate just generate 0.7 V (approx) so a stack of 250 to 1000 bipolar plates are necessary for powering one car.
There are several types of fuel cell: Alkaline Fuel cell (AFC), Direct Methanol Fuel cell (DMFC), Phosphoric Acid Fuel cell (PAFC), Proton Exchange Membrane Fuel Cell (PEMFC)... and not only Hydrogen is used, also Methanol and Methane are used on fuel cells
