The catalytic reaction in the hydrogen fuel cell
The catalytic reaction in the hydrogen fuel cell formed when the current drawn increasing attention of scientists and engineers, fuel cells have become the batteries of portable devices to choose from. Currently, the developers are speeding up the development of the use of fuel cells as power train and car.
The most important application of a fuel cell does not produce harmful emissions advantage, because the reaction of hydrogen and oxygen the only product is water. But the catalyst life is limited, the use of traditional technology for the hydrogen contains more carbon monoxide impurities, impurities can cause carbon monoxide catalyst is "poisoned", so that the catalyst lost its activity. Scientists want to solve this problem early in the platinum (catalyst main component) to add such as ruthenium or other metal molybdenum.
Dr. Ma Hajia proposed a new hydrogen purification reaction, in response to the use of ruthenium chloride (or some other metal) contact and nitrogen compounds as a catalyst, these compounds can be dissolved in water - methanol solvent, so rich in carbon monoxide, hydrogen impurities through the water - methanol. Reaction can not 80 ~ 150 ℃ high temperature for the reaction of carbon monoxide into carbon dioxide in the oxidation before and was almost 100% recovery. Moreover, in the course of this reaction will form additional hydrogen, because the oxidation of water molecules involved in the process. Total reaction time of only a few seconds, resulting in millions of hydrogen molecules in carbon monoxide molecules only a few left.
