New Hydrogen Fuel Purification to boost Hydrogen Fuel Cell Efficiency

Hydrogen is considered to be a promising clean energy source in the near future. It is one of the cleanest sources of energy. In addition, it offers zero emissions and high energy conversion efficiency.  However, the major hurdle in the mass adoption of hydrogen cell is carbon monoxide. It damages the fuel cell electrodes and, thus reduces the life span of the cell. Presently, hydrogen is synthesized from the steam reforming of hydrocarbons. The hydrogen derived from the reaction usually contains 0.5 to 2 percent of traces of CO. These CO traces further contaminate the electrodes of hydrogen cell. This results in the decreased battery life and reduced performance. This restrict the application of fuel cells in vehicles.

New Technique to Contribute in Commercialization of Hydrogen Cell

A team of researchers have devised a new technique to purify hydrogen fuel at temperatures in the range from 198 to 380 degree Kelvin. The technique involves design of a new structure of atomically spread iron hydroxide to purify hydrogen cell.  It protect the cell against CO poisoning during frequent cold starts and continuous operation in extremely low temperatures. The technique helps in the selective removal of CO present in the hydrogen cell. The technique is cost effective and helps in 100 percent removal of CO from the fuel cell.

Earlier, scientist used preferential oxidation method to purify hydrogen cell. But the technique was not effective at cold temperatures. The new finding will majorly help in the usage of hydrogen fuel in vehicles.
