What are disadvantages of fuel cells?

Disadvantages of using fuel cells in cars hydrogen is in the gas state at room temperature and pressure, so it is difficult to store in the car. fuel cells and electric motors are less durable than petrol engines and diesel engines, so they are not so long-lasting. fuel cells are very expensive.

What is the most serious drawback to fuel cells?

The most serious drawback to fuel cells is the expense of providing an oxygen source. Wood and charcoal burning is still the main energy source for about 30 percent of the world’s population. In favorable locations wind power is cheaper than other new energy sources.

What are advantages and disadvantages of using fuel cells?

Hydrogen Fuel Cell Advantages and Disadvantages in Material…

  • Hydrogen Fuel Cell Technology.
  • Advantage: High Energy Density Improves Productivity.
  • Disadvantage: The Use of Fossil Fuels in Hydrogen Production.
  • Disadvantage: Hydrogen Storage and Transportation.
  • Disadvantage: Fuel Cell Efficiency.

What is the problem with fuel cells?

The two prime dangers from fuel cell and hydrogen-powered vehicles are the danger of electrical shock and the flammability of the fuel. Fuel cells power vehicles by electro-chemically combining hydrogen gas (H2) and oxygen (O2) from the surrounding air into water (H20) and electrical energy.

Are fuel cells safe?

They produce zero emissions from the tailpipe and can deliver 300 miles or more per tank of fuel. They can be refilled as fast — or faster — than a conventional car with a 15-gallon gas tank. After extensive testing, researchers say they are as safe to drive as gasoline cars.

Do fuel cells degrade over time?

A container for hydrogen and a fuel cell, on the other hand, do not degrade over time. Furthermore, once batteries are fully charged, they continuously “leak” energy when not in use, while a container of hydrogen does not leak and has a longer shelf-life.

What is the first problem with fuel cells?

They have yielded almost no products that can compete with conventional power sources, at least without subsidies and tax credits. Major impediments to fuel cell commercialization include insufficient longevity, reliability, and, in many cases, unacceptably high cost.

How long does a fuel cell last?

The fuel cell stacks are designed to last the lifetime of the vehicle, about 150,000–200,000 miles. At the end of its lifespan, the fuel cell will be disassembled and the materials recycled, similar to what happens with vehicle components today. A fuel cell stack is about the size of a roll-aboard suitcase.

How much does a fuel cell cost?

In contrast to these battery costs, operators reported an average cost of $33,000 for a fuel cell system for Class I and II lifts (typically 8–10 kW in size), with costs ranging from $32,000 to $34,000.

Why are batteries better than fuel cells?

The biggest difference between the two is that a battery stores energy, while a fuel cell generates energy by converting available fuel. A fuel cell can have a battery as a system component to store the electricity it’s generating. Essentially, there is a small explosion as the fuel is combusted.

Does fuel cell have a future?

In the future, fuel cells could power our cars, with hydrogen replacing the petroleum fuel that is used in most vehicles today. Unlike a typical battery, which eventually goes dead, a fuel cell continues to produce energy as long as fuel and oxidant are supplied.
