Original text[edit]

Electrons are drawn from the anode to the cathode through an external circuit, producing direct current electricity. As the main difference among fuel cell types is the electrolyte, fuel cells are classified by the type of electrolyte they use.

The anode catalyst, which breaks down the fuel into electrons and ions. The anode catalyst is usually made up of very fine platinum powder.
The cathode catalyst, which turns the ions into the waste chemicals like water or carbon dioxide. The cathode catalyst is often made up of nickel but it can also be a nanomaterial-based catalyst.

A typical fuel cell produces a voltage from 0.6 V to 0.7 V at full rated load. Voltage decreases as current increases, due to several factors:

Revised text[edit]

Electrons are drawn from the anode to the cathode through an external circuit, producing direct current electricity. As the main difference among fuel cell types is the electrolyte, fuel cells are classified by the type of electrolyte (any substance which forms ions in an aqueous solution) they use.

The anode catalyst, which breaks down the fuel into electrons and ions. The anode catalyst is usually made up of very fine platinum powder.The anode has a negative charge.

The cathode catalyst, which turns the ions into the waste chemicals like water or carbon dioxide. The cathode catalyst is often made up of nickel but it can also be a nanomaterial-based catalyst. The cathode has a positive charge.

A typical fuel cell produces a voltage from 0.6 V to 0.7 V at full rated load. Voltage decreases as current increases, due to several factors. Voltage is measured in volts (or joules per coulomb), while current is measured in amperes (or coulombs per unit of time):

Comments[edit]

The wording and details have been phrased in a more interesting and reader friendly way. I see that the anode and cathode catalyst are broken into two bullets, however the first sentence in both of the bullets do not read well, they seem like incomplete sentences. I would suggest to ditch the comma and which. This allows the sentence to flow better....at least when I read it in my head...and that should not be taken for too much as I often read things weird in my head :) Good Job!

I like that you added that the anode has a negative charge and that the cathode has a positive charge. If you could add what you said in class about the cathode being pawsitive as an easier way to remember this fact, it would be great!
Perhaps you should add that the cathode is positive and the anode negative for galvanic cells only when running in the spontaneous direction. In electrolysis, the cathode has a negative charge, and the anode has a positive charge.
Finally, the original text looks like it is leading up to mention something about factors that cause voltage to decrease as current increases. Is this a mistake in the original page? "Voltage decreases as current increases, due to several factors:" Your version mentions the factors, but does not list what they are (as far as I can see).
