This item permits measurements concerning conversion of light power into electrical energy.
The light energy produced by a 75 W lamp(similar to solar energy) is converted into electrical power by a photovoltaic panel.
This electrical energy is used to separate, thanks to a PEM electrolytic cell, (Proton Exchange Membrane) water molecules in the constituent components (with an increase in chemical potential energy contained in hydrogen and oxygen gases).
The two gases are mixed again through a PEM fuel cell, producing water and electric energy again, which is used to operate a fan (mechanical energy) by a small electric motor. The two PEM cells are identical and are both used as electro-chemical converters, once in a direction and then in the opposite.
The measurement of electrical quantities can be performed by means of two multimeters. it is possible to detect as vary the electrical quantities during the operation, making use of voltage and current sensors.
