Hydrogen fuel cells, is quite optimistic about the future of energy in the 21st century, in the past has been used in space technology, as the spacecraft after launch, the electronic equipment used in electric power, how will future use in everyday life? Take you to learn.

A fuel cell is an energy directly from the fuel oxidation reaction, generating means power, "hydrogen" is a very common fuel, hydrogen is composed of electrons and protons, when the hydrogen enters the fuel cell anode, it will be separated into protons and electrons, electrons flowing from the circuit, will produce the electricity, and the proton through the electrolyte will eventually arrive at the same time to the cathode and electrons, and oxygen reaction becomes water vapor, and then discharged into the air by an equation expression; "hydrogen + oxygen = electricity + water", while a small part of the energy at the time of conversion to heat dissipation way, because it is by a chemical reaction to produce electricity, so that the fuel cell is referred to as battery.

ITRI ​​Dr. Cao Fanghai: "I have talked about, the real energy is the fuel, and that this in itself can be a lot like fuel, fossil energy is energy which a fuel cell can also use fossil fuels, but the fuel cell can also be the use of hydrogen produced by the water inside, from a lot of biomass material, a lot of waste from the inside, brought some hydrogen to, so it does not necessarily need to rely on fossil fuels. "

Scientists in the past will be the first fuel cell, used in space technology, hydrogen and oxygen is often used as the shuttle's power source, spacecraft after liftoff, astronauts use of electronic instruments and electric power, it is supplied by the fuel cells and solar power generation After water, the water can become a daily astronauts, past the fuel cell to help people complete, fly to the universe's magnificent dream.

Now the fuel cell, used in everyday life, can be a fuel cell locomotive itself can be used as is a portable generator, the locomotive's power is turned on, the hydrogen bottle of hydrogen through the pipeline, to the fuel cell generated electricity, for general use appliances, so it is possible to anywhere, free to use, load wattage of 1300 watts of electrical, fuel cells directly via a chemical reaction to generate electricity, the combustion of the fuel is hydrogen, it does not produce any pollutant, it is a very clean energy.

Dr. ITRI 曹芳海: "Because it is an electrochemical reaction, and is hydrogen as the main fuel, so it is actually the only byproduct heat with water only, it has no other by-products, that we can re-use the heat Water may also be used to use either in a loop, so it is also much less polluting than traditional techniques. "

But fuel cell catalyst material is platinum, but also to the high price of fuel cells, the next step to think about how to make large-scale power generation in order to reduce costs. (FTV news roundup)
