Fuel cells for electric vehicles
Fuel cells are galvanic cells, which perform the function of an energy converter by converting chemical to electrical energy. The fuel cells available at ARADEX are hydrogen-oxygen fuel cells.
The main advantage of fuel cells is, besides the extremely quiet and reliable application, the very high efficiency.
Within the framework of our successful cooperation with the fuel cell manufacturer "Proton Motor Fuel Cell", fuel cells can be supplied via ARADEX in addition to all other components of electrical drive systems.
- Through our proven business connections, we can supply high-quality manufacturers with a wide range of fuel cell options to complement your overall system in the most sensible and efficient way.
- The combination of fuel cells from Proton Motor Fuel Cell and the VP5000 DC / DC converter from ARADEX is an optimized solution for voltage boosting or voltage swing.
Fuel cells - the basic technology & frequently used types
In a hydrogen-oxygen fuel cell are located water and oxygen molecules separated by a thin membrane. The hydrogen molecules function as fuel, the oxygen molecules as oxidizing agents. Both the hydrogen and the oxygen molecules are arranged around an electrode (anode or cathode). The hydrogen molecules each emit an electron to the anode and thereby become a proton (H2 becomes H +), as a result of which they can penetrate the membrane and reach the oxygen molecules. At the same time, the electron released by the electrodes now runs through the electrodes and thus also reaches the region of the oxygen molecules. Once there, a compound is formed with an oxygen atom and reduced to O2-. In connection with the proton penetrated by the membrane, water is produced, and electric current is generated by the flow of electrons through the electrodes.
The advantage of energy generation by a fuel cell compared to conventional combustion is that the fuel cell can convert chemical energy directly into electrical energy and does not first convert into heat (thermal energy), which must then be converted into electrical energy by a generator. As a result, considerable losses in energy conversion remain unaffected.
Today, fuel cells are used both in electromobility and in stationary applications.
