The energy produced by a fuel cell depends on its type, size, and application. For example, a typical hydrogen fuel cell can produce about 0.5 to 1 volt per cell, with power output ranging from a few watts in small applications to several megawatts in larger installations. Overall efficiency can be around 40-60% for converting chemical energy to electrical energy, potentially rising to 80-90% when waste heat is utilized in combined heat and power systems.

How much coal has to be burned to produce the same amount of energy as is generated by a kilogram of uranium fuel pellet?
Approximately 30,000 kilograms of coal would need to be burned to produce the same amount of energy as is generated by a kilogram of uranium fuel pellet. Uranium fuel has a much higher energy density than coal, making it a more efficient and cleaner source of energy.
Uranium fuel pellet used in nuclear power stations produce far more energy per kilogram than the energy produced by burning coal How much coal has to be burnt to produce the same amount of energy as?
1 kg of U-235 will produce as much energy as 1500 tons of coal
What carbohydrate do for your body?
carbohydrates breaks down to polysachorides->mono...-sugar> energy for the body to run => fuel of energy biol.242
How much energy does it take to make ethanol fuel?
The energy required to produce ethanol fuel varies depending on the production process, but it typically takes about 0.25-0.3 kWh of energy to produce one liter of ethanol. This includes energy inputs for growing and harvesting the feedstock, processing it into ethanol, and distilling the ethanol.
How does the reaction of hydrogen and oxygen to produce energy in a fuel cell differ from their interaction during the direct combustion of hydrogen and oxygen?
In a fuel cell, the reaction of hydrogen and oxygen occurs electrochemically, producing electricity as a byproduct. This process is more efficient and produces less waste compared to direct combustion of hydrogen and oxygen, which releases energy in the form of heat without generating electricity. Fuel cells offer a cleaner and more controlled way to harness energy from hydrogen compared to combustion.
How much electricity does a single fuel cell generate?
The electricity generated by a single fuel cell can vary widely depending on its size, type, and application. For example, a small portable fuel cell may produce around 1 to 5 watts, while larger stationary fuel cells can generate several kilowatts (kW) or even megawatts (MW) for industrial applications. The efficiency and output also depend on the fuel used and the design of the fuel cell system. Overall, fuel cells can be tailored to meet specific power needs, ranging from small devices to large-scale energy systems.
Does nuclear fuel produce sixty eight percent of the electrical energy in US?
No, much less, about 20 percent at present
What is renewable alternative to coal?
You can use many different things. some examples are: Bio-Fuel (still in development) Wind (not as reliable as coal) solar (doesn't produce as much energy as coal) hydro (doesn't produce as much energy as coal)
How much fossil fuel energy is used to produce 100 MW of electricity to a town?
i gotta do same question for my science assignment
Why do carbohydrates in the mitochondria produce more ATP than those outside the cell?
Because oxidation is complete. Much energy is conserved.
How much less carbon dioxide do fuel cell cars emit?
Fuel cell cars use hydrogen to drive the fuel cell in the car which generates electricity. The only emissions are water and heat. No carbon dioxide at all. (The production of the hydrogen will have a carbon footprint, unless it was produced using renewable energy.)
