the spotlight. Hydrogen energy system bases an ideal principle which hydrogenis produced from water and returns tothe original substance; water after being used. We can expect that after 2010, the cost ofhydrogen as one ofthe resources should be lower than that of fossil fuel. Fuelcellisthe bright prospective technique and it already spreads out in many industrial field like hydrogenfuele
andhydrogen over the other, and it generates electricity, water and heat. Fuelcells chemically combine the molecules of a fueland oxidizer without pollution of traditional combustion.
In a fuelcell, the electricity is generated directly as an electrochemical device andtherefore, there is no high-temperature step as normal burning. This direct conversion of chemical energy to electrical e
of storage for capacitors rose, higher level of electricity application became possible to realize.
(ex) Uninterruptible(UPS), Hybrid automobile
supercapacitors have a lot in common with batteries, but we can say that they arethe newest form of battery.
You can charge it in a very short period of time and repeat a number of charge and discharge periods.
The energy efficiency is muc
cell through reactions between a fueland an oxidant, triggered inthe presence of an electrolyte.
Fuelcells are direct energy conversion into electricity. So High electric conversion efficiency and carbon dioxide reduction is excellent.
Since 1999, A joint research for 2 years
after all, Succeed in first development
A small fuelcell, hydrogen tank, control equi
and Mechanism ofHydrogen Production
Uptake hydrogenases are Ni-Fe enzymes that catalyze the conversion ofhydrogen gas tohydrogen ions and electrons. They are found inthe heterocysts and not inthe vegetative cells of nitrogen-fixing strains of cyanobacteria. They remove thehydrogen gas produced by nitrogenase when they carry out nitrogen fixation.
Uptake hydrogenase is encoded by
