When refulling a hydrogen powered car what precautions should you take?
An education. With an education, you would realize that the concept is to store power chemically. You would also realize that this is the same concept behind batteries, and behind gasoline/diesel. You would realize that the hydrogen oxygen reaction is just the simplest reaction to use in such a storage scheme and not necessarily the best one for various reasons. You would realize that hydrogen is very voluminous hence using hydrogen to store energy requires large pressure tanks, you would realize that diatomic hydrogen is the second smallest gas molecule and will diffuse slowly through any material, you would realize that current fuel cells require pure hydrogen and pure oxygen or the membranes would clog up, and you would realize that replacing a significant portion of the one billion vehicles out there with hydrogen vehicles would represent a significant environmental impact in itself. Hydrogen is just particularly marketable to the laymen because almost everyone has seen the grade s
