Mobil water charger
Battery low ? give him some water...
green fuel cell technology which cleanly and efficiently converts
hydrogen into electricity. Unlike
solar chargers, fuel cell power is generated quickly (no waiting for sun
harvesting) and reliably (speed of charging not impacted by weather,
solar position etc. and no power degradation like batteries).
technology. Made from foils and adhesives, these
FuelCellStickers form a flexible assembly less than 2.75mm thick. Since
the hydrogen fuel can be supplied from several alternative sources, the
system is “flexifuel”.
What is fuel cell technology and how does it work?
A fuel cell is an electrochemical device that transforms the chemical energy of a fuel (hydrogen, methanol, natural gas, gasoline etc.) and an oxidant (air or oxygen) into electrical energy. The fuel and the oxidant react at two different electrodes – the anode and the cathode – and are separated by an electrolyte that transmits ions (e.g. H+, OH- etc.) from one electrode to the other.
Fuel cells have many similarities with batteries,but with the fundamental difference that the electrodes are not consumed in the process – a fuel cell will run as long as fuel and oxidant (air) is provided to the electrodes.
There are two primary areas where the environmental potential of hydrogen is especially significant: in transportation and as an interim storage of renewable energy. Through the use of hydrogen together with fuel cell technology it is possible to achieve a radical decrease in local pollution of carbon dioxide, nitrogen oxides and particles from the transportation sector.
Although the production of hydrogen from fossil fuels affects the environment it is an advantage that the carbon dioxide emissions can be separated already on the production site. This becomes evident when hydrogen is used as vehicle fuel, avoiding pollution from every individual vehicle.
The only emission from a fuel cell reacting with hydrogen is pure water. The environmental gains are high, provided that pollution in the hydrogen production process is kept low. A fuel cell is approximately twice as energy efficient as a combustion engine if used in a regular car. The effect is that, using the same amount of energy, a fuel cell car can drive twice as far as a car with a combustion engine can. Modern batteries have even lower energy losses than those of fuel cells. However, these need to be recharged and are relatively heavy. Therefore, a combination of batteries and fuel cells can be advantageous in many areas, particularly in vehicles. For example, the reach of an electric car of family size is up to 500-600 kilometers of pollution free driving, since the fuel cells recharge the battery while the car is in use.
Note:
The fuel cell
inside a completely passive system. Without fans or
pumps, the fuel cell silently converts hydrogen into electricity via its
Proton Exchange Membrane.
The chemistry process is safe, controllable and eco-friendly, and the only bi-product from the fuel cell is a little water vapor. To operate, hydrogen must be supplied to the fuel cell, and the fuel cell must be exposed to the open air.

hydrogen
Hydrogen is the lightest and most abundant chemical element, constituting roughly 75 percent of the universe’s chemical element mass. Today a large amount of hydrogen is used as raw material in industries. In the future hydrogen may also play an important role in society’s transformation from fossil fuels to renewable alternatives. Hydrogen powered fuel cells can power anything from cars and boats to cell phones and computers. They can also be used to supply electricity and to heat houses.How does hydrogen effect the environment?
Hydrogen is an alternative energy carrier to fossil fuels and oil. The magnitude of the environmental gains possible through the use of hydrogen as an energy carrier depends on how the hydrogen is produced and transported, as well as how efficiently it is transformed.There are two primary areas where the environmental potential of hydrogen is especially significant: in transportation and as an interim storage of renewable energy. Through the use of hydrogen together with fuel cell technology it is possible to achieve a radical decrease in local pollution of carbon dioxide, nitrogen oxides and particles from the transportation sector.
