What is the problem with fuel cell vehicles?

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.

Why are fuel cell cars better?

Fuel cell electric vehicles (FCEVs) are powered by hydrogen. They are more efficient than conventional internal combustion engine vehicles and produce no tailpipe emissions—they only emit water vapor and warm air.

How long do car fuel cells 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.

How much does a fuel cell cost?

These equipment costs were generally offset by a federal tax credit available for fuel cell systems, set at the lesser of $3,000/kW or 30\% of the cost. For an average system costing $33,000, this tax credit reduces the effective cost of the fuel cell system by about $10,000.

Are fuel cells the future?

In the future, fuel cells could power our cars, with hydrogen replacing the petroleum fuel that is used in most vehicles today. Fuel cells have strong benefits over conventional combustion-based technologies currently used in many power plants and cars.

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.

How long does a fuel cell last?

Are fuel cells different from batteries justify?

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 is different. It takes an energy source, such as propane, diesel or natural gas, and converts it into electrical energy.
