Fuel Cells that Run off Ethanol or Sugar Possible?

In summary, while some fuel cells can run on hydrogen and oxygen, others can also run on methane and carbon monoxide. However, direct usage of ethanol is not possible and it must be reformed into methane for use. It is uncertain if sugar can be reformed for use in fuel cells.

Is it possible to make fuel cells that run of ethanol or even sugar? :confused:


Is it a good idea? Why/Why not?

PEMFC fuel cells and a few others can only run on H2 and O2. Solid oxide fuel cells can run on CH4, CO and H2.

Although direct usage of ethanol is not possible, usage by reforming it to convert it into methane is possible. I don't know whether reforming of sugar is possible or not.

Sugar probably wouldn't be very efficient because it caries oxygen, but I thought the following formula was interesting

C6H12O6 ---> 2 (C3H6O3) + Energy
 

1. What is a fuel cell?

A fuel cell is a device that converts the chemical energy of a fuel, such as ethanol or sugar, into electricity through a chemical reaction.

2. How do fuel cells that run off ethanol or sugar work?

Fuel cells that run off ethanol or sugar use a process called electrochemical oxidation to convert the chemical energy in these fuels into electricity. This involves breaking down the fuel molecules into smaller components and using the energy released to power an electrical current.

3. What are the benefits of using fuel cells that run off ethanol or sugar?

One of the main benefits of using fuel cells that run off ethanol or sugar is that they produce much less pollution compared to traditional fossil fuel-powered engines. They also have higher energy efficiency and can be refueled quickly and easily.

4. What are the limitations of fuel cells that run off ethanol or sugar?

The main limitation of using fuel cells that run off ethanol or sugar is the availability and cost of these fuels. Ethanol and sugar are not as readily available as traditional fossil fuels, and their production can be expensive. Additionally, the infrastructure for refueling these fuel cells is not as extensive as that for traditional fuel sources.

5. Are there any current applications for fuel cells that run off ethanol or sugar?

Yes, there are currently several applications for fuel cells that run off ethanol or sugar. They are commonly used in small portable devices, such as cell phones and laptops, as well as in some larger vehicles like buses and forklifts. They are also being researched and developed for use in homes and buildings as a more sustainable and efficient energy source.
