Renewable Energies and Smart Grid » Fuel Cells

Fuel cells are devices that produce electricity by a chemical reaction taking place at the electrodes (anode and cathode). Hydrogen is the basic fuel but the fuel cells also require oxygen. They generate electricity with very little pollution; much of the hydrogen and oxygen used in the generating electricity combine to form a harmless byproduct (water). A fuel cell provides a DC voltage that can be used to power motors, lights or any number of electrical appliances. For this field, De Lorenzo provides different trainers. A basic kit, to study the principles and the operation of PEM full cells, is available to be used in physics and chemistry classes as well as in technology classes. Two other trainers, for medium and high levels, can be chosen to study in depth this technology. For the medium level, the Solid Oxide Electrolyser Cell (SOEC) is energized by a solar panel to produce hydrogen and oxygen and the high level’s trainer is supplied with a hydrogen canister (with hydrogen already stored), sensors and PEM fuel cell, of a certain power, to analyze in detail its performance. For the latter trainer and to load the canister, a hydrogen generator is available as an option. These last are also supplied complete with software for data acquisition and processing. They are dedicated to schools, high schools and first years of university according to the level.
