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 are fuel cells?
fuel cells are the hydrogen fuel cell that operates similar to a battery. It has two electrodes, an anode and a cathode, separated by a membrane.fuel cell is a type of an electro-chemical cell which can convert the fuel energy into electrical energy by reactions of oxidized and fuel particles triggered in the presence of electrolyte
How does fuel cell differ from a battery?
A fuel cell is different from a battery cell in so far as reactants are constantly supplied to a fuel cell making it an open system whereas a battery cell is a closed system that stores the reactants within it. A fuel cell works as long as fuel is supplied to it whereas a battery cell requires regular replacements.
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.
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.
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 only byproduct of fuel cells?
The only byproduct of an oxygen and hydrogen fuel cell is water. There are other less common types of fuel cells, such as zinc and air cells, which do produce other byproducts.
What is a fuel cell?
Fuel cells are capable of converting fuel directly to electrical energy. All of the fuel cells currently in production are relatively expensive and considerably less than perfect, especially since they get so hot and waste electricity.There are a few different types of fuel cells. Some run on hydrogen, others on methane.Special gas tank used in race cars.A fuel cell refers to a cell producing electric current directly, this is usually from a chemical reaction.
What is the waste product of fuel cells?
In a normal hydrogen oxygen fuel cell, the waste products are water, and heat
Is Hydrogen Fuel Cells supposed to be capitalized?
No. Hydrogen fuel cell is not a title. You would only capitalize hydrogen if it was at the beginning of a sentence, as I did with this one. Otherwise, you would say 'hydrogen fuel cell'.
What is the fuel used in a fuel-cell automobile?
Fuel cells come in many varieties. Low-temperature designs such as proton exchange membrane fuel cells [PEMFC's, also known as polymer electrolyte membrane fuel cells] are mostly aimed at portable and transport applications
