Fuel Cells

One of the biggest precautions that needs to be taken when you fix the water fuel cell in cars is to protect yourself against electrocution. This involves using the appropriate safety equipment, such as insulating shoes and gloves.

It doesn't.

A problem with fuel cell cars is that hydrogen is not readily available in pure form

Hydrogen fuel cells are used in various applications, including transportation, stationary power generation, and backup power systems. They power vehicles such as buses, trucks, and forklifts, offering a zero-emission alternative to conventional fuels. Additionally, fuel cells are employed in remote power generation and as backup power sources for critical infrastructure. Their versatility and environmental benefits make them a key technology in the transition to cleaner energy solutions.

As of 2023, the cost per kilowatt output of fuel cells typically ranges from $2,000 to $4,000, depending on the type of fuel cell and its application. This cost can vary significantly based on factors such as scale of production, technology advancements, and specific use cases. Ongoing research and development efforts aim to reduce these costs further, making fuel cells more competitive with other energy technologies.

One company commercially offers fuel cell power plants for about $3,000 per kilowatt.

A fuel cell is an electrochemical device that converts chemical energy from a fuel, typically hydrogen, and an oxidant, usually oxygen, into electricity through a chemical reaction. Unlike batteries, which store energy, fuel cells generate electricity continuously as long as fuel is supplied. They are known for their high efficiency and low emissions, making them a promising technology for clean energy applications. Fuel cells are used in various applications, including vehicles, stationary power generation, and portable power devices.

diasadvantages... low efficiency

cant learn every individual move of the system but i know what the fuel cell will be good for

00.89%

A car that runs on fuel cells only has a similar overall efficiency to a car that runs on petrol because a car that runs on fuel cells is designed to not pollute the Earth but you need renewable energy resources to generate the electricity which is like the efficiency of the petrol pollution.

That was what I put on my homework anywayz. :)

• In Nelson's cell, an aqueous solution of concentrated NaCl is used for the industrial production of NaOH, while in Down's cell fused or molten NaCl is used for obtaining sodium metal
• In Nelson's cell, three main chemicals are obtained as products that are Hydrogen gas, Chlorine gas and NaOH whereas in down's cell chlorine gas and sodium metal is produced as a product.
• In Down's cell, graphite is used as anode and iron is used as cathode. But, in Nelson's cell perforated steels is made cathode and grapite as anode.

hydrogen

I expect you are thinking of hydrogen. It's not that we don't have plenty of ways to make it, indeed we do that, in vast quantities, to manufacture fertilizers, margarine etc. The problem is that we make it from natural gas, a fossil fuel, and there's no point to the fuel cell if it doesn't replace fossil fuel use. We can also make hydrogen by electrolysis, but that requires electricity, and therefore a way of making electricity, so doing that without burning fossil fuels becomes the issue.

The cost of a fuel cell car typically ranges from $50,000 to $70,000, depending on the make and model. Some models may be eligible for government incentives or rebates that can help reduce the purchase price. As the technology develops and production scales up, prices may decrease over time. However, upfront costs remain relatively high compared to traditional gasoline vehicles.

A fuel cell works exactly the same way a battery works. Unlike a battery, the hydrogen comes from a tank and is put into the cathode. Rather than dissolve the cathode as is done in a battery, new fuel is fed into the cathode. An electron is removed from the hydrogen atom at the cathode. it is then sent through a wire. The nucleus of the hydrogen atom becomes the positively charged particle and functions as the positively charged particle just like in a battery. And just like from a battery, the electron goes to a motor, a battery, or some other device. It comes back to the anode where it is added to an oxygen atom. The Oxygen atom gains two electrons and becomes a negatively charged ion. Then two hydrogen and one oxygen atoms join together in the center and become water. The procedure can be made warm enough so the water is given off as steam.

Hydrogen gas

the product in hydrogen cells is not a greenhouse gas

The product in the fuel cell reaction is not a greenhouse gas - apex :)

I am not able to give you a cost, as there are a number of fuel cell technologies, and it will be difficult to know which ones might ultimately become commercial. So far, fuel cells applications have required large government subsidies.

The "hydrogen car" is still apparently a long ways from becoming a reality- see related links.

Hydrogen fuel cells have been in use since the 19th century, with the first practical fuel cell developed by Sir William Grove in 1839. However, they gained significant attention and development during the 20th century, particularly in the 1960s for space applications. Since then, hydrogen fuel cells have been increasingly adopted for various uses, including transportation and stationary power generation, as interest in clean energy technologies has grown.
