Question

Why are fuel cells not being used in daily
life despite their very high efficiency?

1. The fuels needed for their
operation are rarely found in
nature

2. Their operation always needs very
high temperature

3. The catalyst used in fuel cells at
normal temperature are very
expensive

4. The design of fuel cells is so
complicated that it is not feasible
to construct these for daily life application ​

Answer 1

Answer:

hii. !!

Explanation:

At present, industrial hydrogen is predominantly obtained directly from natural gas. However, the fuel cell does not really have any environmental advantages with this kind of fuel, either. ... Electricity is then produced from hydrogen again in the car. This double conversion significantly reduces the efficiency level....

hope this helps u ✌️ ❤️❤️

Answer 2

Final answer: Fuel cells not being used in daily life despite their very high efficiency.

Given that: We are given the fuel cell.

To find: We have to find Why fuel cells are not being used in daily

life despite their very high efficiency.

Explanation:

• Fuel cells are the electrochemical cell in which chemical energy of the fuel is converted to electrical energy.

• These cell possess very high efficiency (75-90%). They are also very light. Do not create pollution problems.
• But fuel cell are not being used in our daily life.

• The fuel used in the common fuel cells are hydrogen and oxygen. Compared to other gases hydrogen is not easily available in atmosphere. Hence cost of production is high.

• Changes in temperature affect the electrochemical reaction and fuel cell efficiency. Greater fuel cell efficiency happen at high temperature.

• Most widely used catalyst in fuel cell is platinum it is very expensive.

• Distribution of hydrogen is one of the main problem. Cost reduction and long durability are the major challenge for designing fuel cell.
