Both fuel cells and primary cells are devices that convert chemical energy into electrical energy. The main difference is that primary cells use stored chemical energy in the form of a non-rechargeable chemical reaction, while fuel cells continuously receive fuel and an oxidizing agent to generate electricity through a controlled chemical reaction.

What is the main difference between a fuel cell and a voltaic cell?
A fuel cell generates electricity from a chemical reaction between a fuel source and an oxidizing agent, without requiring any recharging. A voltaic cell is a device that generates electricity from a spontaneous chemical reaction between two different metals or materials, which eventually stops producing electricity as the reactants are consumed.
What does an electrolyte do in a fuel cell?
Electrolytes in a fuel cell help facilitate the movement of ions between the electrodes, allowing the flow of electricity to be generated. They help maintain the charge balance within the cell by conducting ions, which are crucial for the cell's overall operation.
What is the relationship between CNG density and its impact on fuel efficiency in vehicles?
The relationship between CNG density and its impact on fuel efficiency in vehicles is that higher CNG density typically leads to better fuel efficiency. This is because denser CNG contains more energy per volume, allowing vehicles to travel further on less fuel.
What is the by-product of a fuel cell?
The by-product of a fuel cell is typically water vapor. This is because fuel cells generate electricity through a chemical reaction between hydrogen and oxygen, producing electricity, heat, and water as a result.
Is sodium hydroxide a electrolyte in fuel cell?
Yes, sodium hydroxide is an electrolyte commonly used in fuel cells. It helps to facilitate the flow of ions between the electrodes, allowing the fuel cell to generate electricity efficiently.
Is a fuel cell a primary cell or secondary cell?
A fuel cell is neither a primary cell nor a secondary cell; it operates on a different principle. While primary cells provide electrical energy from a chemical reaction and cannot be recharged, and secondary cells can be recharged after discharging, fuel cells generate electricity through an ongoing reaction between fuel (like hydrogen) and an oxidizer (like oxygen). This process continues as long as fuel is supplied, making fuel cells a unique energy source.
What is the main difference between a fuel cell and a voltaic cell?
A fuel cell generates electricity from a chemical reaction between a fuel source and an oxidizing agent, without requiring any recharging. A voltaic cell is a device that generates electricity from a spontaneous chemical reaction between two different metals or materials, which eventually stops producing electricity as the reactants are consumed.
What is the primary fuel for the brain in-between meals?
Glucose assuming you have normal hours in between meals. Your livers and muscles have glucose stores (glycogen) that fuel the hours in between meals.
What is the relationship between fossil fuel and humans?
You use it to put fuel in your car and heat your home with the energy it produces.
What is the relationship between cc and hp?
There is no set relationship between cc and hp. there are many factors that influence it, such as fuel type, compression ration and ignition temperature.
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 does an electrolyte do in a fuel cell?
Electrolytes in a fuel cell help facilitate the movement of ions between the electrodes, allowing the flow of electricity to be generated. They help maintain the charge balance within the cell by conducting ions, which are crucial for the cell's overall operation.
What is the relationship between CNG density and its impact on fuel efficiency in vehicles?
The relationship between CNG density and its impact on fuel efficiency in vehicles is that higher CNG density typically leads to better fuel efficiency. This is because denser CNG contains more energy per volume, allowing vehicles to travel further on less fuel.
What is the basic difference between solar cells and fuel cells?
A fuel cell is an electrochemical energy conversion device whiles a solar cell is a device that converts photons from the sun into electricity.
What is the primary fuel of main sequence stars?
The primary fuel for all stars is hydrogen
What is the by-product of a fuel cell?
The by-product of a fuel cell is typically water vapor. This is because fuel cells generate electricity through a chemical reaction between hydrogen and oxygen, producing electricity, heat, and water as a result.
Is sodium hydroxide a electrolyte in fuel cell?
Yes, sodium hydroxide is an electrolyte commonly used in fuel cells. It helps to facilitate the flow of ions between the electrodes, allowing the fuel cell to generate electricity efficiently.
