Unfortunately, costs down. Fortunately, I had previously designed a 90 unless you are a well-funded university watt PEM fuel cell, as well as a 400 watt PEM electrolyzer. Both were only on paper, and had yet to be or a large corporation, purchasing a fuel proven. The designs seemed to be a good match for cell or hydrogen electrolyzer has been supplying adequate power and fuel to the remote- controlled model car the students wanted to power. The next to impossible. car is a small, 7.4 volt unit that weighs about 6 or 7 pounds (3 kg). I’ve studied and researched fuel cells and hydrogen for several years, and I find them fascinating and Materials technically challenging. It was always frustrating The heart of any PEM fuel cell or electrolyzer is the to learn only from books, without any hands- membrane.
