Which of the following is a disadvantage of using batteries over fuel cells?

The choice indicating that batteries have a limited number of recharge cycles accurately reflects a key disadvantage of using batteries compared to fuel cells. Each time a battery is charged and discharged, there is a gradual decline in its ability to hold a charge due to chemical degradation processes occurring within the battery. This limits the number of times a battery can be effectively recharged before it needs to be replaced, making it less sustainable for long-term use compared to fuel cells, which can operate continuously as long as they have a constant supply of fuel.

In contrast to this, the other choices present characteristics that are either advantages of batteries or things that don’t accurately represent the limitations of battery technology. For example, the statement concerning lasting indefinitely is not true for batteries, as they have a finite lifespan. Similarly, the assertion about being unable to recharge also does not hold, since many types of batteries are designed to be rechargeably used multiple times within their lifespan. The claim regarding pollution is more favorable towards fuel cells, as they typically result in lower emissions than batteries, especially considering the production and disposal impacts associated with battery materials.
