Fuel cells rescued by batteries
Fuel cells were originally considered to be replacements for internal combustion engines used in traditional vehicles and replacements for traction batteries used in pure electric vehicles. Unfortunately, they have proved woefully incapable of efficiently and economically supporting the frequent load changes of vehicle traction. Many of them had a troublesome start up time and problems of life and reliability as well. Thus building ever larger fuel cells was pursued from about 1991 to 2001 but it ended in tears.
