In a fuel cell, when hydrogen gas is supplied to the anode, the hydrogen molecules are split into protons and electrons. The electrons travel through an external circuit to the cathode, creating an electric current. At the cathode, oxygen molecules combine with protons and electrons to form water. So, electrons play a key role in generating electricity in a fuel cell.
What else can I help you with?
What process is oxygen involved in?
Oxygen is involved in the process of cellular respiration, where it serves as the final electron acceptor in the electron transport chain to produce ATP (energy) in cells. It is also essential for the process of aerobic metabolism in which glucose is broken down to produce energy for the cell.
Why electron move from anode to cathode in microbial fuel cell?
Electrons flow from the anode to the cathode in a microbial fuel cell as a result of the electrochemical reactions occurring at the electrodes. During the oxidation of organic matter at the anode, electrons are released and travel through an external circuit to the cathode, where reduction reactions occur. This electron flow generates a current that can be harnessed for electricity production.
What is the Use of sodium acetate in microbial fuel cell?
Sodium acetate can be used as a carbon source in microbial fuel cells to provide a substrate for microbial growth and electron transfer. The acetate is metabolized by the microbes, generating electrons that can be transferred to an electrode to produce electricity. Sodium acetate can therefore enhance the performance and efficiency of microbial fuel cells.
Is a fuel cell a secondary cell?
No, a fuel cell is not considered a secondary cell. Fuel cells generate electricity through a chemical reaction involving a fuel source and an oxidizing agent, without the need for recharging like secondary cells, such as batteries.
Why is it correct to classify the fuel cell that you have costructed as a voltaic cell?
A fuel cell operates based on the same principle as a voltaic cell; it generates electricity through a chemical reaction. In a fuel cell, chemical energy from the fuel is directly converted to electrical energy without combustion, making it similar to a voltaic cell that uses redox reactions to generate electrical energy. Therefore, it is correct to classify a fuel cell as a type of voltaic cell.
What two forms of energy are involved in fuel cell technology?
Chemical and electrical
Where in a plant cell would you find the electron transport systems that are involved in the final stage of aerobic respiration?
In the Mitochondria
What process is oxygen involved in?

Which subatomic particles is involved in chemical reactions?
They are all 'involved', but the one which changes its environment is the electron.
Where in the mitochondrion does the electron transport chain?
The electron transport chain takes place in the inner mitochondrial membrane. This is where the series of protein complexes and molecules work together to generate ATP through electron transfer and proton pumping.
Why electron move from anode to cathode in microbial fuel cell?
Electrons flow from the anode to the cathode in a microbial fuel cell as a result of the electrochemical reactions occurring at the electrodes. During the oxidation of organic matter at the anode, electrons are released and travel through an external circuit to the cathode, where reduction reactions occur. This electron flow generates a current that can be harnessed for electricity production.
How is a fuel cell different from a typical cell?
A fuel cell oxidizes a fuel source, a standard cell is an electrochemical reaction.
What is the largest atom molecule cell electron?
Cell.
What reacts inside a cell's mitochondria to produce carbon dioxide water and energy?
Main fuel is glucose. Oxygen is needed for burning,as last electron acceptor.
What is the Use of sodium acetate in microbial fuel cell?

The acetate is metabolized by the microbes, generating electrons that can be transferred to an electrode to produce electricity. Sodium acetate can therefore enhance the performance and efficiency of microbial fuel cells.
Centrioles might be observed in some of these cells with an electron microscope In which cells would these be observed and what is the function of these cell organelles?
Centrioles are found in animal cells and are involved in organizing the microtubules that make up the cell's cytoskeleton. They play a key role in cell division by ensuring proper chromosome segregation.
What is fuel for a cell?
The fuel for a cell is made up of oxygen and hydrogen. The chemical energy produced by the two is what is converted to serve as fuel for the cell.
