Ответ:
Hydrogen gas is volatile.
Explanation: The limitation of the fuel cell for which the people are concerned is that hydrogen gas is volatile and the cars at high speed might crash.
This property of the fuel cell is a limitation because hydrogen is volatile at room temperature and can be made non volatile at lower temperatures which is not possible when it is used as a fuel.
