Hybrid installations for converting fuel energy into electricity are a promising way to provide humanity with affordable energy resources. However, the issue of obtaining reagents (hydrogen and oxygen) with high purity remains one of the most urgent. In this work, the energy characteristics of a hydrogen-oxygen fuel cell in combination with a water electrolyzer were investigated. Membrane-electrode assemblies were formed consisting of a modified membrane based on polytetrafluoroethylene with a platinum-containing component (Pt(30%)/C), as well as an anode and cathode made of carbon fabric and porous nickel doped with technical carbon and graphene. The structural characteristics of the material were studied using the scanning electron microscopy method. For the first time the investigation of hydrogen-oxygen membrane-electrode assemblies energy characteristics was carried out on an automated electronic load AKIP-1375/1E with embedded software. In the developed hydrogen-oxygen fuel cell, a more affordable commercial polytetrafluoroethylene-based membrane was used as a solid polymer elec-trolyte instead of the Nafion membrane, which significantly reduced the cost of developed MEA. As a result of the tests carried out, it was found that the maximum specific power is demonstrated by elements constructed on the basis of an anode and a cathode made of porous nickel modified with graphene.
