Ch4 Fuel Cell

This is much cleaner than octane and more efficient.

Ch4 fuel cell.

I don t get how to get the n value to plug into delta g nfe. 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 methane as fuel.

Methane takes up much less space than hydrogen and would be more practical to store in fuel tanks. Learners planet 75 443 views. The contaminants included were fuel impurities co co 2 h 2 s and nh 3. 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.

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. It was found that even trace amounts of impurities present in either fuel. 6 methane natural gas fuel cell. Fuel cell cars are very similar to traditional gasoline powered cars.

Take methane and make a fuel cell that adds oxygen to the ch4 and generate electricity 4 water molecules and 1 carbon dioxide molecule. This paper reviewed over 150 articles on the subject of the effect of contamination on pem fuel cell. The material catalyzes an oxidation process that releases carbon dioxide electrons and protons. A robust fuel cell operated on nearly dry methane at 500 c enabled by synergistic thermal catalysis and electrocatalysis.

Air pollutants no x so x co and co 2. They can refuel in just a few minutes and the fueling experience is almost identical to a gas station. A fuel cell by contrast can mix hydrogen with air to produce electricity at up to 60 per cent efficiency. And cationic ions fe 3 and cu 2 resulting from the corrosion of fuel cell stack system components.

Fuel cell hydrogen oxygen fuel cell hydrocarbon oxygen fuel cell 12 csbe electrochemistry duration. The protons then react with oxygen at the cathode to produce water.
