Direct methanol fuel cell pdf.

The mea and prototype delivered at the. Direct methanol fuel cells have attracted extensive attentions from the fuel cell community because it is regarded as a promising candidate to replace the traditional power sources for portable. A direct methanol fuel cell dmfc is an electrochemical energy conversion device that converts the chemical energy of liquid methanol into electrical energy directly. The direct methanol fuel cell dmfc has been considered as the ideal fuel cell system since it produces electric power by the direct conversion of the methanol fuel at the fuel cell anode.

Direct methanol fuel cell is still in the development phase and expected to cover major share in the fuel cell market. Direct methanol fuel cell technology for portable power relevance to and synergy with larger fuel cell systems market entry with power sources sold today at 1 000 10 000 kw is likely to happen first experience with specialized cell structures and materials as well as bop elements e g sensors and control could be relevant to the larger systems. In contrast to indirect methanol fuel cells where methanol is reacted to hydrogen by steam reforming dmfcs use a methanol solution usually around 1m i e. 1 reduce noble catalyst loading and cost.

2 enhance cathode tolerance of methanol poisoning. A passive air breathing liquid feed direct methanol fuel cell dmfc with no external pumps or other auxiliary devices was designed fabricated and tested with different methanol concentrations. Common operating temperatures are in the range 50 120 c where high temperatures are usually pressurized dmfcs themselves are more efficient at high temperatures and. Three critical challenges from material to system levels.

Due to its unique advantages such as a higher energy density facile liquid fuel storage capability and simpler system structure the direct methanol fuel cell has been. Methanol the fuel of dmfcs has such. Stationary direct methanol fuel cells dmfcs using pure methanol as the fuel. About 3 in mass to carry the reactant into the cell.

We have developed 1 kw output direct methanol fuel cell dmfc successfully which is the highest output level in the world in this kind of fuel cell. 3 decrease methanol crossover.
