Ethanol is an attractive alternative to methanol because it comes with a supply chain that's already in place. Ethanol also remains the easier fuel to work with for widespread use by consumers. Ethanol is a hydrogen-rich liquid and it has a high energy density (8.0 kWh/kg) compared to methanol (6.1 kWh/kg
In most fuel cell configurations with liquid feeds, the fuel and oxidizing solutions almost always contain water which acts as a diffusion medium. In many hydrogen-oxygen fuel cells, the diffusion of oxygen at the cathode is rate limiting since the diffusivity of oxygen in water is much lower than that of hydrogen.
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]
It's developing a fuel cell system that will use bio-ethanol (generated from crops like corn and sugarcane) as a hydrogen source when it reaches vehicles in 2020. ... Hydrogen fuel cell cars are ...
The technology uses heat to reform ethanol into hydrogen to feed what is known as a solid oxide fuel cell (SOFC). The fuel cell generates electricity to supply power to the electric motor driving the wheels, through a battery that handles peak power demands and stores regenerated energy.
The OorjaPac Model T is a liquid fuel cell that is tailored to meet the needs of the telecommunication industry. [16] Oorja Protonics also has the OorjaRig™, a refueling system that stores and delivers methanol to the OorjaPac™ on-board charging system that is designed for indoor use in commercial and industrial environments.

A flaming cocktail works by burning ethanol (grain alcohol), a type of liquid fuel also found in all alcoholic drinks. Liquid fuels are combustible or energy-generating molecules that can be harnessed to create mechanical energy, usually producing kinetic energy; they also must take the shape of their container. It is the fumes of liquid fuels ...
Direct methanol fuel cell Their main advantage is low temperature operation and the ease of transport of methanol, an energy-dense yet reasonably stable liquid at all environmental conditions. Whilst the thermodynamic theoretical energy conversion efficiency of a DMFC is 97%; [ 1 ] as of 2014 the achievable energy conversion efficiency for ...
