Development of supercapacitors for the storage of energy from microbial fuel cells. Potential applications in portable devices and led luminaires in rural areas

Due to the impacts of climate change generated by the greenhouse gases used by the use of fossil fuels for the generation of electrical energy, the energy deficiency present in rural areas of Peru, the deprivation of the internet as a fundamental right of the humanity of the communities from rural areas; it is necessary to implement energy storage devices coupled to intermittent and environmentally friendly energy systems such as fuel cells. Faced with this reality, the need arises to design advanced materials that allow this energy to be accumulated and can be used in LED lighting and the operation of internet routing devices. In this sense, this research project proposes the development of hybrid systems based on carbon fabrics modified with graphene oxide and impregnated with conductive polymers and / or metal oxides. These materials have high surface areas and load storage capacity. Reduced graphene oxide contributes to increase the surface area of ​​carbon fabrics, as well as its capacity to store charge, the three-dimensional arrangement of reduced graphene oxide with mesoporous metal oxides could provide the system with greater charge storage, reaching values ​​of high capacitance, which could be used in electrochemical capacitors, allowing the energy from microbial fuel cells to be stored quickly. The developed capacitors are expected to be able to store the energy necessary for the operation of a router device and / or LED luminaire.
