This paper reviewed over 150 articles on the subject of the effect of contamination on pem fuel cell.
Ch4 fuel cell.
Methane takes up much less space than hydrogen and would be more practical to store in fuel tanks.
And cationic ions fe 3 and cu 2 resulting from the corrosion of fuel cell stack system components.
They can refuel in just a few minutes and the fueling experience is almost identical to a gas station.

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.
I don t get how to get the n value to plug into delta g nfe.
The contaminants included were fuel impurities co co 2 h 2 s and nh 3.
Fuel cell hydrogen oxygen fuel cell hydrocarbon oxygen fuel cell 12 csbe electrochemistry duration.
The material catalyzes an oxidation process that releases carbon dioxide electrons and protons.
Consider a fuel cell that uses methane as fuel.
A robust fuel cell operated on nearly dry methane at 500 c enabled by synergistic thermal catalysis and electrocatalysis.
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.
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.
The protons then react with oxygen at the cathode to produce water.
Fuel cell cars are very similar to traditional gasoline powered cars.
The delta g is 818 kj.
This is much cleaner than octane and more efficient.
