Ch4 Fuel Cell

It was found that even trace amounts of impurities present in either fuel.

Ch4 fuel cell.

Take methane and make a fuel cell that adds oxygen to the ch4 and generate electricity 4 water molecules and 1 carbon dioxide molecule. The team covalently attached a low temperature methane activating platinum catalyst to conductive carbon and used the material as a fuel cell anode. Fuel cell cars are very similar to traditional gasoline powered cars. This is much cleaner than octane and more efficient.

A fuel cell by contrast can mix hydrogen with air to produce electricity at up to 60 per cent efficiency. The delta g is 818 kj. The contaminants included were fuel impurities co co 2 h 2 s and nh 3. The protons then react with oxygen at the cathode to produce water.

Methane takes up much less space than hydrogen and would be more practical to store in fuel tanks. Fcevs also present relatively low barriers to entry in terms of societal changes as they operate and perform similarly to conventional vehicles refuelling at stations in minutes and driving for 500 to 600 kilometres on a single tank. The chemical reaction is ch 4 2o 2 2h 2 o co 2 energy a 0 5 measurements reveal that deltah for this reaction is 890 kj for each mole of methane processed assuming standard temperature and pressure t 298 k p 100 kpa. Consider a fuel cell that uses the reaction ch4 g 2o2 g co2 g 2h2o l given the standard free energies of the formation in appendix b what is the value of e.

This paper reviewed over 150 articles on the subject of the effect of contamination on pem fuel cell. Fuel cell hydrogen oxygen fuel cell hydrocarbon oxygen fuel cell 12 csbe electrochemistry duration. Methane is first reformed to co and h2 within the fuel cell and then the h2 and co are electrochemically oxidized to h2o and co2 on the electrode the lower temperature fuel cell would allow ordinary stainless steel rather than exotic materials to be used for the interconnectors that link the cells into a stack. A robust fuel cell operated on nearly dry methane at 500 c enabled by synergistic thermal catalysis and electrocatalysis.

Learners planet 75 443 views. They can refuel in just a few minutes and the fueling experience is almost identical to a gas station. 6 methane natural gas fuel cell. Similar to today s gasoline vehicles fuel cell electric cars can have a driving range of more than 300 miles on one tank of hydrogen fuel.

Consider a fuel cell that uses methane as fuel. I don t get how to get the n value to plug into delta g nfe.
