No, not all fuel cells run on hydrogen. While hydrogen fuel cells are the most common and widely recognized type, other fuels can also be used, such as methanol, natural gas, and even biogas in different types of fuel cells. Each type has its specific design and application, depending on the fuel source and the intended use.
There are two problems with hydrogen fuel cells. One is that the cars that run off of hydrogen fuel cells are very expensive to make another thing is that hydrogen storage is not easy. The work and money it would take to put up hydrogen stations around the country for cars is too much to even consider it. Also another problem with hydrogen is te oil companies that don't wanna lose their business.
no, they just mean that the engine has a supply of hydrogen to run on rather than any other fuel
Fuels cells are essentially not very dangerous. But in order for a fuel cell to work hydrogen must be used. Hydrogen is usually fed to a fuel cell from a resevoir. Hydrogen is very flammable and if the concentration in an area of hydrogen is too great any spark of any kind even friction can make it combust. Not all fuel cells run on hydrogen. There are natural gas and methanol cells. Fuel cells are dangerous to your life if you are making one in your basement workshop and don't tell your significant other what you're doing and what it costs first. This is because the membrane in a fuel cell, a DuPont film called Nafion, costs $175 per square foot and it looks like that plastic you make document protectors from. "YOU SPENT $200 ON THIS!?!?!?!?!"
Fuel cells are capable of converting fuel directly to electrical energy. All of the fuel cells currently in production are relatively expensive and considerably less than perfect, especially since they get so hot and waste electricity.There are a few different types of fuel cells. Some run on hydrogen, others on methane.Special gas tank used in race cars.A fuel cell refers to a cell producing electric current directly, this is usually from a chemical reaction.
A gasoline engine cannot run on hydrogen alone without significant modifications. Hydrogen has different combustion properties than gasoline, requiring changes to the fuel delivery system, ignition timing, and possibly the engine's internal components to handle the different combustion characteristics and temperatures. Some engines can be converted to run on hydrogen, but this typically involves adapting them to function as hydrogen internal combustion engines or using fuel cells instead.
no because it needs fuel and hydrogen does not have everything in the combustion triangle
No. That is when stars run out of hydrogen. They then have helium for fuel.
A hydrogen vehicle is an alternative fuel vehicle that uses hydrogen as its onboard fuel for motive power. The term may refer to a personal transportation vehicle, such as an automobile, or any other vehicle that uses hydrogen in a similar fashion, such as an aircraft. The power plants of such vehicles convert the chemical energy of hydrogen to mechanical energy either by burning hydrogen in an internal combustion engine, or by reacting hydrogen with oxygen in a fuel cell to run electric motors. Widespread use of hydrogen for fueling transportation is a key element of a proposed hydrogen economy.
It typically takes around 10 billion years for a star like the sun to consume all its hydrogen fuel and enter a different phase of its life cycle. The exact duration can vary depending on the size and type of the star.
The hydrogen fuel cell operates similar to a battery. It has two electrodes, an anode and a cathode, separated by a membrane. Oxygen passes over one electrode and hydrogen over the other.The hydrogen reacts to a catalyst on the electrode anode that converts the hydrogen gas into negatively charged electrons (e-) and positively charged ions.The electrons flow out of the cell to be used as electrical energy. The hydrogen ions move through the electrolyte membrane to the cathode electrode where they combine with oxygen and the electrons to produce water. Unlike batteries, fuel cells never run out. In principle, a fuel cell operates like a battery. Unlike a battery, a fuel cell does not run down or require recharging. It will produce energy in the form of electricity and heat as long as fuel is supplied.
Yes, all stars run on a limited suppliy of fuel - mainly hydrogen. Some stars burn it very quickly but reach high temperatures, while other lower mass stars burn their fuel more slowly, lasting for longer, but burn at cooler temperatures.
