Development and Characterization of an Ecological Hydrogen Stove

In this work we developed and evaluated an ecological stove for food cooking, using hydrogen as the fuel. The operation of the device consists mainly of a renewable energy source, such as a photovoltaic system, which produces the electricity needed to power a bipolar alkaline electrolyzer from 1 kW to 1.9 kW, consisting of 85 stainless steel electrodes, which generates hydrogen for combustion in the cooking system. The prototype evaluation consisted of two main stages. In the first phase the operating parameters of the electrolyzer were obtained, achieving an efficiency of 60 to 77%, gas production from 3 to 6 L / min, with a maximum operating time of 395 minutes. The second phase focused on the cooking system, where the thermal efficiency of the device was determined, as 61.5%.
