which of these is a major drawback of using fuel cells in a car?\n○ a lack of hydrogen filling stations\n○ a drop in reliance on petroleum products\n○ an increase in water vapor into the atmosphere\n○ an increase in the use of rechargeable batteries

Answer

Brief Explanations:

  • a lack of hydrogen filling stations: This is a major drawback as it limits the practicality and convenience of using fuel - cell cars. Without a sufficient infrastructure of hydrogen - refueling points, it is difficult for consumers to adopt fuel - cell vehicles widely.
  • a drop in reliance on petroleum products: This is actually a positive aspect as it reduces dependence on non - renewable and polluting fossil fuels.
  • an increase in water vapor into the atmosphere: Water vapor is a relatively benign by - product compared to harmful pollutants from internal combustion engines. And in the context of the overall environmental impact, it is not a major drawback.
  • an increase in the use of rechargeable batteries: Fuel - cell cars do not primarily rely on rechargeable batteries in the same way as pure electric vehicles. This option is not relevant to the main drawback of fuel - cell cars.

Answer:

a lack of hydrogen filling stations
