Materials used and the list goes on and on. Use the search engine to limit your reading on this or other forums. Anyone selling something always says his product is better but..... Use some basic rules to keep yourself from getting a piece of junk.
Start with systems that have not less than 6 cells per stack.
There is areas that are in dispute where there are competing technologies but the basics are pretty much set. The most important matter is in the end how will the reactor and whole system holds up over time. After being on a vehicle for a few months will it leak, melt, plates get eaten up, damage your throttle body because of electrolyte in the gas and this is just to name a few. A lot of sellers have no long term studies to prove that there products last and only quote customers good reports not the bad ones. Their warranties are worthless in almost all cases. This is my opinion anyway based on experience. You can only protect yourself with knowledge.
