Fuel cells to the fore
Article Abstract:
More compact proton-exchange membrane (PEM) hydrogen fuel-cell systems are coming to the fore as the suitable battery to propel electric vehicles (EVs). This battery technology delivers impressive energy performance, high conversion efficiency, low emissions and quick startup and rapid response to transients. But similar to other conventional battery technologies, PEM fuel-cell systems are also faced with commercialization challenges. The cost of PEM fuel-cell batteries must come down before it can truly be competitive with the internal combustion engine. Present development in fuel-cell technology must pay attention not only to performance but also to cost.

Engineering the EV future
Article Abstract:
The development of electric vehicles (EVs) is moving into high gear due to continuing damage to the environment brought by cars powered by internal combustion engines (ICEs). EVs have yet to enter mainstream due to the absence of the ideal batteries to propel them. A number of battery technologies have been developed or being improved, including nickel-metal hydride batteries and hydrogen fuel cells. Meanwhile, there are hybrid electric vehicles (HEVs), which have long been considered as having the potential to be commercially viable. However, HEVs are regarded by the pure EVs proponents as a temporary solution.
