BackgroundWorldwide, hydrogen is being regarded as a fuel of the future due to its abundance and the byproducts generated by its combustion. However, mass production of hydrogen gas is a problem complex, since it entails large energy costs. In this work, three prototypes, based on standard and low cost materials, for the production of hydrogen were used, varying the way of generating hydrogen by electrolysis and the way of using the hydrogen produced, either by storing it or to be use in

The system of rectangular plates with bipolar dry cell electrolyzer obtained a H2 generation of 0.1 m3/hr with an energy consumption of 553.6 [kW/m3 H2] operating at 2 [atm], on the other hand, the unipolar collector with points generated 0.02 m3/hr 20/60 standard liters per H2 with a consumption of 144 [kW/m3] operating at 1 [atm] this was the most efficient device with a 26 % efficiency considering the solar energy used.ConclusionA low cost prototype was created which allows the use of solar energy, allowing the energy storage in the form of H2. It can be used in a rural area to be injected in kitchen burners, reducing LPG (liquefied petroleoum gas) consumptions and contributing to the sustainable development.
