In this work is analyzed the Greenhouse Gases production (GHG) by combustion of binary and ternary mixtures, in a 5500 W portable engine generator of alternating current ; connecting to the generator three electric charges as a dynamic brake. It were measured the decrements in the production of CO, HC and NOx of up to 99%, 93% and 67%, respectively, as well as an increment in CO2 up to 35%; in addition, reduction in uptake fuel of more than 36%. Therefore, the reduction of GHG emissions will improve the quality of air in the cities, at the same time the quality of people’s health.

The regenerative hydrogen/vanadium fuel cell (RHVFC) is investigated with Freudenberg carbon paper electrodes (CPs). Along with thermal treatment, the Freudenberg CPs are also treated with reduced graphene oxide (rGO) using electrophoretic deposition at 300 V. The rGO modified CP results in 25% higher power density than its untreated counterpart under the same operating conditions. In comparison to the first preliminary study, the power density reported herein is more than four times higher. Additionally, the Freudenberg CPs modified with heat treatment followed by rGO deposition facing the membrane (rGOHTFM) provide the best electrolyte discharge utilization (UE) of 99%, followed by untreated (98%) and heat treated samples (97%) at 50 mA cm-2. The rGOHTFM also record high charge and discharge energy efficiencies (ηE) of 93% at the same current density, which is slightly higher than untreated CPs (ηE = 91%). Cycling the system 10 times also results in higher ηE and UE for rGOHTFM CP (ηE = 92% and UE = 99% on average) in comparison to untreated electrodes (ηE = 86% and UE = 97% on average). In comparison the widely investigated SGL 10AA CP has lower efficiencies and utilization as expected (ηE = 74% and UE = 83% on average).
