Portable Direct Methanol Fuel Cell

Currently direct methanol fuel cell technology is being incorporated into a system for portable.

Portable direct methanol fuel cell.

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. About 3 in mass to carry the reactant into the cell. Portable direct methanol fuel cell systems s. Our fuel cell technology is a modular solution that is highly flexible scalable and customisable.

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. A direct methanol fuel cell dmfc is an electrochemical cell that generates electricity based on the oxidation of methanol and reduction of oxygen. 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. Valdez jet propulsion laboratory pasadena ca 91 109 1 o introduction the advantages of methanol as a high energy fuel and the system simplicity offered by the process of direct oxidation at ambient temperatures makes the direct methanol fuel.

1 to power portable electronics devices 2 to provide alternative power generators for rural homes schools or hospitals with limited access to grid power. An aqueous methanol solution of low molarity acts as the reducing agent that traverses the anode flow field. A five cell direct methanol fuel cell stack has been developed at the jet propulsion laboratory. This technology uses methanol as source of energy.

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.
