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. about 3% in mass) to carry the reactant into the cell; common operating temperatures are in the range 50 to 120 °C (122 to 248 °F), where high temperatures are usually pressurized.
Proton-exchange membrane fuel cells (PEMFC), also known as polymer electrolyte membrane (PEM) fuel cells, are a type of fuel cell being developed mainly for transport applications, as well as for stationary fuel-cell applications and portable fuel-cell applications. Their distinguishing features include lower temperature/pressure ranges (50 to ...
Demonstration model of a direct methanol fuel cell (black layered cube) in its enclosure Scheme of a proton-conducting fuel cell. A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) [1] into electricity through a pair of redox reactions. [2]
As the steam reforming of methanol is more simple and efficient (catalyst bed temperature below 280°C) compared to reforming of other fuels and because of the low cost and high purity of conventional methanol and renewable methanol (e.g. made from waste or renewable power) as well as because of the simple storage of methanol, most HT-PEM fuel ...
Methanol fuel. Methanol fuel is an alternative biofuel for internal combustion and other engines, either in combination with gasoline or independently. Methanol (CH 3 OH) is less expensive to sustainably produce than ethanol fuel, although it is more toxic than ethanol and has a lower energy density than gasoline.
SFC Energy is a manufacturer of direct methanol and hydrogen fuel cells based in Brunnthal near Munich. The company also develops solutions [buzzword] for off-grid and stationary power generation and distribution. This also includes the production of voltage converters and switching power supplies. [1]
Oorja Fuel Cells. Oorja Fuel Cells (Oorja Protonics Inc) is an energy company that designs, manufactures, and commercializes direct methanol fuel cells for use in the logistics, automotive, distributed generation (micro-grid), and telecommunication industries. Oorja develops direct methanol fuel cells ranging in power from 0.5 to 100 kilowatts.
A solid oxide fuel cell (or SOFC) is an electrochemical conversion device that produces electricity directly from oxidizing a fuel. Fuel cells are characterized by their electrolyte material; the SOFC has a solid oxide or ceramic electrolyte. Advantages of this class of fuel cells include high combined heat and power efficiency, long-term ...
