True or False? A PEM fuel cell needs to operate at very high temperatures.

To determine

The truth of the given statement.

Explanation

Given information:

A PEM fuel cell needs to operate at very high temperature.

Hydrogen is used as source of energy in fuel cells. It is used as fuel for running electric vehicles. It is present in form of a compound, for example hydrogen and oxygen combine to form water. Hydrogen and carbon combines in stochiometric ratio to form hydrocarbons.

Hydrogen can be separated from hydrocarbons by using reformers. Reformers help in extracting hydrogen by using a high temperature steam. It can also be separated by using electrolysis. Reformers can extract hydrogen from gasoline, methanol and natural gases. PEM works more efficiently when it is operated at a lower temperature...
