What fuel is used in SOFC?

What fuel is used in SOFC?

Comparison of four primary types of fuel cells. Fuel : PEM fuel cells use pure hydrogen (H2) as fuel. Meanwhile, solid oxide fuel cells can use hydrocarbon fuels such as natural gas, methane and propane to produce electricity.

Can ethanol be used in fuel cell?

e-Bio Fuel-Cell is a fuel cell system that uses bioethanol (100% ethanol or an ethanol-blended water) as a fuel source to generate electricity through the Solid-Oxide Fuel Cell (SOFC).

How does an ethanol fuel cell work?

The DEFC, similar to the DMFC, relies upon the oxidation of ethanol on a catalyst layer to form carbon dioxide. Water is consumed at the anode and is produced at the cathode. Protons (H+) are transported across the proton exchange membrane to the cathode where they react with oxygen to produce water.

Which fuel cell is the best?

Alkaline Fuel Cells Operating at 60-70ºC (140-158ºF), AFCs are among the most efficient type of fuel cells, reaching up to 60% efficiency and up to 87% combined heat and power. Both the US and Russian/Soviet spaceships used alkaline fuel cells to produce electricity and drinking water for astronauts.

How big is a direct ethanol fuel cell?

Various prototypes of Direct Ethanol Fuel Cell Stack mobile phone chargers were built featuring voltages from 2V to 7V and powers from 800 mW to 2W were built and tested. ^ Badwal, S.P.S.; Giddey, S.; Kulkarni, A.; Goel, J.; Basu, S. (May 2015). “Direct ethanol fuel cells for transport and stationary applications – A comprehensive review”.

Can a Lt ‐ SOFC be fueled by liquid alcohol?

Direct operation of LT‐SOFCs on liquid alcohol fuels can further improve their portability as well as accessibility to the fuel. In this review, we overview the results of LT‐SOFCs directly fueled by liquid alcohols that operate at 600 °C and below.

Why does DEFC use ethanol instead of methanol?

They have been used as a model to investigate a range of fuel cell concepts including the use of PEM. DEFC uses Ethanol in the fuel cell instead of the more toxic methanol. Ethanol is an attractive alternative to methanol because it comes with a supply chain that’s already in place.

How does ethanol improve the performance of a fuel cell?

Recently, it has been reported that a significant improvement in cell performance has been achieved as a result of the rapid kinetics of ethanol electrooxidation by changing the acid electrolyte to alkaline (i.e., hydroxide exchange ionomer and hydroxide exchange membrane).
