Ch4 Fuel Cell

The material catalyzes an oxidation process that releases carbon dioxide electrons and protons.

Ch4 fuel cell.

Fuel cell hydrogen oxygen fuel cell hydrocarbon oxygen fuel cell 12 csbe electrochemistry duration. Consider a fuel cell that uses methane as fuel. A fuel cell by contrast can mix hydrogen with air to produce electricity at up to 60 per cent efficiency. This paper reviewed over 150 articles on the subject of the effect of contamination on pem fuel cell.

Methane takes up much less space than hydrogen and would be more practical to store in fuel tanks. 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. The team covalently attached a low temperature methane activating platinum catalyst to conductive carbon and used the material as a fuel cell anode. This is much cleaner than octane and more efficient.

Air pollutants no x so x co and co 2. Fuel cell cars are very similar to traditional gasoline powered cars. It was found that even trace amounts of impurities present in either fuel. 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.

The delta g is 818 kj. And cationic ions fe 3 and cu 2 resulting from the corrosion of fuel cell stack system components. 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. Learners planet 75 443 views.

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 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. 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 contaminants included were fuel impurities co co 2 h 2 s and nh 3.

I don t get how to get the n value to plug into delta g nfe. They can refuel in just a few minutes and the fueling experience is almost identical to a gas station.
