At some point in the first paragraph I would define that PEM means proton exchange membrane. I get that, but the casual reader might be confused as to what the abbreviation is.
You have a run on sentence I the fisrt paragraph. Change the sentence about Nafion to read: “A fluorinated ionomer called Nafion, which is the most widely utilized proton-exchange membrane material used today, was developed by DuPont plastics chemist Walther Grot. Grot also demonstrated its usefulness as an electrochemical separator membrane.”
In the first sentence of applications, take out the phrase “in turn.” It’s just filler words and the sentence is more concise and makes sense without it.
The second sentence in the applications section, “Early PEM fuel-cell applications…” also is a bit of a run-on and could make more sense. I would suggest breaking this into two sentences.
Change “their relatively low operating temperature as well as their ability to start up quickly…” to “their relatively low operating temperature and their ability to start up quickly.” So far through your article you use lots of unnecessary filler words that can make the reader lose the point because the sentences are longer than they need to be. I would watch out for that as you add more information.
“California leads the United States in hydrogen refueling stations with 43, and further investment in the technology is budgeted for.” This sentence seems to end abruptly. Budgeted by who?
“A current are of high research activity instead of “an area of high research activity currently”
