Exploring Fuel Cell Technology for Improved Energy Efficiency in Automobiles

In summary, the conversation is about using units that run on DC to extract O and H from water and use the gases to increase fuel mileage in automobiles. There is a discussion about the efficiency of these units and their potential use in hybrid cars. It is mentioned that some people believe these units work to improve fuel economy, but according to physics, they do not. There are recommendations for using a 'dry cell' from Ebay and avoiding scam sites. It is also mentioned that there have been discussions about this topic on various forums, but it is closely monitored to avoid any false claims. Regarding using these units in hybrid cars, it is noted that it would not significantly improve the car's efficiency as acceleration is where internal combustion engines are least efficient.

I've heard about the units that run on DC and extract O and H from water. The gases are then used on automobles to increase fuel mileage. I'd like to hear the thoughts on energe in and energy out. Also, as hybrids store energy for a finite number of power demands, can these fuel cells do a better job of storing energy and releasing it later?
Thanks
Alex

According to physics these will not work. But a lot of people out there will swear they do work to improve fuel economy... If you want to experiment with one of these, I'd recommend using a 'dry cell' sold on Ebay. Supposedly these units are reaching efficiencies of 70+ percent. Avoid scam sites such as water4gas, etc.

It's been discussed in many threads, including this one: https://www.physicsforums.com/showthread.php?t=251887&page=7

Do a search for more. Please note, however, that we have a very tight leash on discussions where crackpot claims might enter in.

Regarding the question of using this for a hybrid, that isn't currently being done, but it could be. But it would not help the efficiency of the car much because it doesn't change how the energy is used. Hybrid cars use electric motors to take much of the load when cars are accelerating, while a hydrogen-based car would still be using combustion in the engine. Acceleration is where the efficiency of an internal combustion powered car is by far at its worst.
 

What is fuel cell technology?

Fuel cell technology is a type of clean energy technology that converts chemical energy from a fuel, such as hydrogen, into electrical energy. This process produces less pollution and greenhouse gas emissions compared to traditional combustion engines.

How does fuel cell technology improve energy efficiency in automobiles?

Fuel cell technology improves energy efficiency in automobiles by using the chemical reaction between hydrogen and oxygen to produce electricity, which then powers the vehicle's motor. This process is more efficient than traditional combustion engines, which rely on burning fuel to produce energy.

What are the benefits of using fuel cell technology in automobiles?

The benefits of using fuel cell technology in automobiles include reduced emissions, increased energy efficiency, and reduced dependence on fossil fuels. It also has the potential to reduce operating costs for vehicle owners, as hydrogen fuel can be produced from renewable sources.

What are the challenges of implementing fuel cell technology in automobiles?

Some of the challenges of implementing fuel cell technology in automobiles include the high cost of producing and storing hydrogen fuel, limited availability of refueling stations, and the need for significant infrastructure changes. There are also concerns about the safety and durability of fuel cells in vehicles.

Is fuel cell technology the future of automobile transportation?

While fuel cell technology has the potential to play a significant role in reducing emissions and increasing energy efficiency in automobiles, it is not the only solution. Other emerging technologies, such as electric and hybrid vehicles, also have the potential to improve energy efficiency in transportation. It is likely that a combination of these technologies will be used in the future to create a more sustainable transportation system.
