In a fuel cell, a continuously supplied fuel (for example, hydrogen from natural gas) reacts with an oxidant (such as oxygen from air). Water, electricity and heat are generated in the process. This electrochemical reaction is also known as "cold combustion" and is particularly efficient. This is virtually the reverse of electrolysis.
Fuel cells have a number of advantages over conventional drives:
- Indoor and outdoor operation (even at extreme temperatures such as in cold rooms)
- emission-free and quiet
- low space requirements for infrastructure
- High efficiency
- very flexible (modular, scalable)
- fast refueling
- very reliable, robust, low maintenance and long service life
- constant power output
Hydrogen itself is explosive, but light and volatile. Compared to liquid fuels or even batteries, gas therefore does not pose a fundamentally higher risk.
If hydrogen from renewable sources is used as the energy carrier, largely emission-free operation of the fuel cells is possible, with only water vapor being emitted.
If diesel or natural gas are used as fuels, emissions can be significantly reduced, firstly because of the higher efficiency of the systems compared with conventional drive systems, and secondly because of the more favorable emissions balance.
... just a different kind of electric vehicles.
... Zero-Emission Vehicles.
... use fuel cells, both in intralogistics and for backup power.
... fuel cell cars can travel up to 600 km without any loss of power. Refueling takes only a few minutes, just like conventional refueling.
... in power generation with fuel cells are heat and water vapor.
... from fossil fuels (up to 50% less emissions) as well as from renewable energy sources (zero emissions).
... is the iron (Fe), followed by oxygen (O2) and then hydrogen (H2). In the universe, hydrogen is the most abundant element.
