PEM, ANION and MEA membranes for an electrolyzer

[AndrzejBristol]

TL;DR Summary

Building electrolyzer.

Hello,
I wanted to build electrolyzer however during my research I encountered number of different membranes for fuel cells etc.. For example anion membrane , PEM , MEA etc. Have to admit I am getting lost in all of this and would like to know more.

I tried to do my own research and I got to point when I decided to find some information on forum.

From what I understand PEM is a full fuel cell membrane that includes GDL s. Anion membrane will keep oxygen and hydrogen separate. Here is my question. Where can I find some information how for example PEM is made and why?. Is there a book or place where I can find such information?. I don't want to buy pieces and put it together - would like to know exactly how it works. Appreciate help.

This is just brief information and I am trying to find some more detail. For example why gdl is needed and what role does it play etc.. Also I am interested in comparison of different types of fuel cells as well as electrolyzers. Book or article?. Thanks
