A PEM hydrogen generator is a device that produces hydrogen gas from water. The hydrogen gas can then be used to power fuel cells and generate electricity. PEM hydrogen generators are more efficient than traditional hydrogen generators and produce less pollution.
PEM Hydrogen Generator – A Cleaner More Efficient Energy Solution
A PEM hydrogen generator is a device that produces hydrogen gas from water using a process called electrolysis. Electrolysis is a process that uses an electric current to split water molecules into their component parts: hydrogen and oxygen.
A PEM hydrogen generator uses a special type of electrolysis cell called a polymer electrolyte membrane (PEM) cell. PEM cells are made of a thin, plastic-like membrane that is coated with a catalyst, usually platinum. The PEM cell has two electrodes: a anode and a cathode.
When an electric current is passed through the PEM cell, water molecules are split at the anode into hydrogen and oxygen ions. The hydrogen ions then travel through the PEM to the cathode, where they combine with electrons to form hydrogen gas. The oxygen ions combine with water molecules to form oxygen gas, which is released from the PEM cell.
PEM hydrogen generators are a clean and efficient way to produce hydrogen gas. They do not produce any harmful emissions, and the only by-product of the electrolysis process is water. PEM hydrogen generators are also very efficient, able to produce large quantities of hydrogen gas from a small amount of water.
PEM hydrogen generators offer a clean and efficient alternative to traditional methods of producing hydrogen gas. If you are looking for a way to produce hydrogen gas without harming the environment, a pem hydrogen generator is the perfect solution.
How PEM Hydrogen Generator Works
A PEM (Proton Exchange Membrane) hydrogen generator is a fuel cell that uses a solid polymer electrolyte membrane as an electrolyte. The hydrogen ions (H+) are drawn through the electrolyte by an applied voltage.
The PEM fuel cell was invented in the early 19th century by Sir William Grove. He discovered that when hydrogen and oxygen are passed through an electrolyte, they combine to form water and produce an electric current.
The first PEM fuel cell was developed by General Electric in the 1960s. PEM fuel cells are used in a variety of applications, including automobiles, forklifts, and portable generators.
PEM fuel cells have a number of advantages over other types of fuel cells. They are relatively small and lightweight, and can operate at a lower temperature than other fuel cells.
PEM fuel cells are also more efficient than other types of fuel cells. They can convert up to 80% of the chemical energy in the hydrogen fuel to electricity.
PEM fuel cells are also less expensive to manufacture than other types of fuel cells.
The main disadvantage of PEM fuel cells is that they require a constant supply of hydrogen. If the hydrogen supply is interrupted, the fuel cell will stop working.
PEM fuel cells are also sensitive to impurities in the hydrogen fuel. If the hydrogen is not pure, it can damage the fuel cell.
