Usage of methanol?
Methanol is used as: biodiesel transesterification,fuel Cell Hydrogen Carrier,wastewater Denitrification and Transportation Fuel.
What is A voltaic cell in which a fuel substance undergoes oxidation and from which electrical energy is obtained continuously?
You probably mean what is called a fuel cell. This type of unit is being developed for vehicles, it is used in space vehicles especially
Working principle of h2-o2 fuel cell?
Polymer Electrolyte Membrane (PEM) fuel cells used in automobiles-also called Proton Exchange Membrane fuel cells-use hydrogen fuel and oxygen from the air to produce electricity. The diagram to the right shows how a PEM fuel cell works.Most fuel cells designed for use in vehicles produce less than 1.16 volts of electricity-far from enough to power a vehicle. Therefore, multiple cells must be assembled into a fuel cell stack. The potential power generated by a fuel cell stack depends on the number and size of the individual fuel cells that comprise the stack and the surface area of the PEM.
Why are fuel cells used on the space shuttle instead of batteries?
Two reasons:Weight. Batteries are heavier per energy unit than fuel cells.Capacity. Fuel cells can store much more energy than batteries.As a bonus, the weight for the fuel cell fuel reduces the weight of another required consumable: water. The "exhaust" of fuel cells is pure water which astronauts can drink.
How do hydrogen fuel cells work?
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.
What major fuel is used for the cell's activities in the human body?
Cells primarily use carbohydrates, especially glucose, which is broken down during cellular respiration, forming molecules of ATP, which are used by the cells in order to get energy to do work (cellular activities). Cells get energy from ATP molecules when they are broken down into ADP and P, which releases energy.
What is importance of ATP in a cell?
ATP (adenosine triphosphate), is the major fuel in a cell used for anything that requires energy.
What food group is used for activities?
Carbohydrates like rice, bread, cereals give the primary fuel for daily activities. They are broken done to simple forms until it becomes glucose which is the form that the cell can use.
What is the major fuel source for the body which nutrient?
Dietary CHO and fat are the major nutrients used for fuel.
What are the applications of hydrogen fuel cell?
Hydrogen Fuel Cell converts the thermal energy released directly into electrical energy.. This fuel cell was used in the Apollo Programe. It also produces water.....
What a fuel cell is why is it useful in spacecraft?
a fuel cell is a cell that produces electricity they are used to provied power and water for the spacecraft so the space craft could'nt really survive with out fuel cells
What is a nuclear fuel cell?
Today they are used in cars
What is the used in a fuel-cell automobile?
Hydrogen gas
What is the purpose of the mitochondrion?
they are complex organelles in the cell that produce energy via cellular respiration to fuel the cell's activities i used the book master the asvab 21th edition by peterson's
Which kind of fuel does a fuel cell have?
water which is an electrolyte in this case , or hydrogen in the water is used and burned
What is a special molecule that provides energy for a cells activities?
The special kind of molecules that store energy for later use are adenosine triphosphate (ATP) molecules. These molecules store up the energy they get from the mitochondria (kitchen of the cell) in the cell. In the human body, unused energy is stored in the from of glycogen and in plants it is stored as starch.
What major fuels are used for cells activities?
ATP (adenosine triphospate)
