Pretty Porous



Future mobility options – using the example of the fuel cell

We also find porous media in the field of “technology”. The materials used for machines and their accessories are very often porous. This is also the case in vehicles.

How to power vehicles?

1) Engine: Vehicles powered by a combustion engine emit climate-changing CO2 and environmentally harmful pollutants into the atmosphere.

2) Battery: Battery-powered vehicles are powered by electrical energy. The so called electric drive. Either the energy is stored in a battery, which has to be recharged, or via power grids, which permanently supply the required electricity from outside. This is, for example, often the case in public transportation.

3) Hybrid: In the hybrid vehicle, the electric drive is combined with an additional drive, for example via a motor.

4) Fuel cell: Fuel cell vehicles are powered by hydrogen.

In this case, we show porous media using the example of the fuel cell, which is used, among other things, to power vehicles. Hydrogen and oxygen flow in channels through the fuel cell and are transported through various permeable layers to ensure a controlled reaction of the components. The reaction in the fuel cell generates electrical energy, heat and water.
