Portable direct methanol fuel cell.

About 3 in mass to carry the reactant into the cell. A five cell direct methanol fuel cell stack has been developed at the jet propulsion laboratory. An aqueous methanol solution of low molarity acts as the reducing agent that traverses the anode flow field. Direct methanol fuel cell dmfc technology is a further development of the hydrogen polymer electrolyte membrane fuel cell pemfc that is particularly promising for portable electronics and vehicular applications due to the advantages of a liquid fuel.

Request pdf portable direct methanol fuel cell systems the simplicity of the direct electrooxidation of methanol in a polymer electrolyte membrane fuel cell and the technological advances. 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. 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. Our fuel cell technology is a modular solution that is highly flexible scalable and customisable.

A direct methanol fuel cell dmfc is an electrochemical cell that generates electricity based on the oxidation of methanol and reduction of oxygen. The simplicity of the direct electrooxidation of methanol in a polymer electrolyte membrane fuel cell and the technological advances achieved in performance and efficiency in the last 10 years has spurred the development of direct methanol fuel cell dmfc based portable power systems in the power range of 0 1 150 w. This technology uses methanol as source of energy. Currently direct methanol fuel cell technology is being incorporated into a system for portable.

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.
