Water, when pure hydrogen is used. If the likes of longer chain alkanes are used, (which they can be in some), CO2 is generated, however, they are still more efficient than standard cars.
During generation of H2, the waste associated would be (at a guess) Oxygen which is not considered waste really, the poisoned catalyst (after time) be it a molecular catalyst or metal electrode surface, and I think the electrolytes after some time become problematic. In a molecular catalytic hydrogen generative system, you need a sacrificial donor molecule, such as triethylamine or triethanolamine.
What else can I help you with?
Hydrogen-fuelled cars are being developed from these cars there is only one waste product what is it?
The waste product from hydrogen-fueled cars is water vapor, which is emitted as a byproduct of the chemical reaction that occurs in the fuel cell. This makes hydrogen-powered cars a potential environmentally-friendly alternative to traditional gasoline-powered vehicles, as they produce zero harmful emissions.
What is the waste product of fuel cells?
The waste product of fuel cells is typically water and heat. When hydrogen is used as the fuel source, the only byproducts are water vapor and heat, making fuel cells a very clean and efficient energy source.
What are the waste by products of hydrogen fuel cells?
The waste byproducts of hydrogen fuel cells are heat and water vapor. When hydrogen is converted into electricity in a fuel cell through a chemical reaction with oxygen, these are the only emissions produced, making fuel cells a clean and efficient energy source.
What life process produces carbon dioxide as a waste product?
The process of cellular respiration produces carbon dioxide as a waste product. During cellular respiration, cells break down glucose to release energy, with carbon dioxide being produced as a byproduct.
What are the reactants for a hydrogen fuel cell and what is the product?
The reactants for a hydrogen fuel cell are hydrogen gas (H2) and oxygen gas (O2), and the product is water (H2O). The reaction in the fuel cell involves the oxidation of hydrogen at the anode and reduction of oxygen at the cathode, with the flow of electrons creating an electric current.
What is the waste product of cells?
In a normal hydrogen oxygen fuel cell, the waste products are water, and heat
Hydrogen-fuelled cars are being developed from these cars there is only one waste product what is it?
The waste product from hydrogen-fueled cars is water vapor, which is emitted as a byproduct of the chemical reaction that occurs in the fuel cell. This makes hydrogen-powered cars a potential environmentally-friendly alternative to traditional gasoline-powered vehicles, as they produce zero harmful emissions.
Which fuel produces only water as a waste product?
When hydrogen is burned the product is pure water vapor. Here is the equation: 2H2 + O2 = 2H2O
What is the waste product of fuel cells?
The waste product of fuel cells is typically water and heat. When hydrogen is used as the fuel source, the only byproducts are water vapor and heat, making fuel cells a very clean and efficient energy source.
Why is a crabon dioxide considered a waste product of the cell?
Carbon dioxide is considered a waste product of cells because it is produced as a byproduct of cellular respiration, where cells generate energy by breaking down glucose. The carbon dioxide produced needs to be eliminated from the cell to prevent toxic buildup and maintain proper pH balance within the cell.
What are the waste by products of hydrogen fuel cells?
The waste byproducts of hydrogen fuel cells are heat and water vapor. When hydrogen is converted into electricity in a fuel cell through a chemical reaction with oxygen, these are the only emissions produced, making fuel cells a clean and efficient energy source.
What is the by product in Downs cell?
Hydrogen and Chlorine
Does NAD serve as an oxygen acceptor a coenzyme a waste product an end product or an acid acceptor in cell respiration?
NAD is a coenzyme.Its role is as a hydrogen acceptor when it is involved in the oxidation of glucose (cell respiration). Is is written as NAD+, and after accepting hydrogen it becomes the reduced form, NADH.NADH in turn acts as a hydrogen donor when it becomes oxidized to reform NAD+.
What are wastes of hydrogen fuel cells?
combustion of fuel needs O2 so hydrogen fuel cell's combustion formula is: 2 H2 + O2 --> 2 H2O the product (waste) is water molecule
What cell respiration waste product?
Water and CO2.
What Gas produced as a waste of certain bacteria can be used as fuel?
Methane gas is produced as a waste product by certain bacteria during the process of anaerobic digestion. This methane gas can be captured and used as a renewable energy source for fuel, typically in the form of biogas.
Which is an advantage of the hydrogen fuel cell over gasoline engines?
the product in hydrogen cells is not a greenhouse gas can also be: The product in the fuel cell reaction is not a greenhouse gas - apex :)
