Question

hydrogen fuel cells are an alternative energy resource that can be widely used to power fuel cell electric vehicles. which of the following is a disadvantage of using hydrogen as a fuel for vehicles? choose 1 answer: a hydrogen fuel is more difficult and costly to store than petroleum based fuel. b hydrogen fuel cells refuel more slowly than gas or electric vehicles. c hydrogen fuel cells function at a lower consistency than an internal combustion engine. d hydrogen fuel cells offer a lower energy efficiency than lithium ion batteries.

Explanation:

Hydrogen is a light - weight gas and requires high - pressure storage or cryogenic conditions, making it more difficult and costly to store compared to petroleum - based fuels which are liquid and easier to handle. Refueling time for hydrogen fuel cells is not necessarily slower than gas or electric vehicles in all cases. Hydrogen fuel cells can have high consistency in operation. Also, hydrogen fuel cells can have high energy efficiency and are not generally lower than lithium - ion batteries in all aspects.

Answer:

A. Hydrogen fuel is more difficult and costly to store than petroleum based fuel.
