Question 1
A fuel cell experiences a chemical reaction that converts fuels containing hydrogen into electricity. The electric current produced is then aimed outside of the cell to function as a powering agent for an electric motor, or to light a bulb (Fuel Cell & Hydrogen Energy Association, 2019).
Question 2
The primary distinction between a fuel cell and a battery is that batteries store energy that it contains. A fuel cell, on the other hand, produces power by utilizing the various sources of energy around it, such as propane, diesel, or natural gas into electricity (Fuel Cell & Hydrogen Energy Association, 2019).

Question 4
The efficiency of a gasoline-burning engine is extremely low at 20 to 35%. The low-efficiency results due to a high percentage of the energy produced, ending up emitted through the exhaust. The rest of the energy turns pumps, fans, generators, and cooling the engine and in ...
