摘要：Hydrogen does not occur free in nature in useful quantities, but it is manufactured in a number of ways. It can be made from natural gas or it can be made by passing electric current through water with greater efficiency over an internal combustion engine. The same amo unt of hydrogen will take a fuel-cell car at least twice as far as a car running on gasoline.
