Abiotic alkaline cell of Mangifera indica L. cv Haden residues with methyl viologen as electron mediator – Instituto Tecnológico de Tuxtla Gutiérrez / CIESEM Center for Research and Social, Economic and Market Studies of the Private Sector, Mexico

There is a growing demand to develop electrical energy methods at low cost and in a sustainable way. A new clean energy source, abiotic alkaline cells is expected to be a next generation power device with many advantages such as low pollution and high efficiency. Abiotic alkaline cells are systems that allow the generation of electrical energy using organic compounds, strong bases, and mediators that aid in the transfer of electrons. The residual biomass from agricultural processes has not been explored so far as a substrate for this type of cells. Agricultural residues are substrates with the presence of polymeric carbohydrates that, under basic conditions, generate monomeric aldoses, susceptible to oxidation, generating electrons. The aldoses generated under basic conditions are oxidized to carboxylic acids, which when decarboxylated, transfer electrons to the medium. So it is of interest to know the effect of the concentration of potassium hydroxide, the residue of Mangifera indica cv Haden, and the mediator (methyl viologen), in the generation of electrical energy in an abiotic cell with agricultural residues as substrate. They will define the appropriate conditions to obtain the maximum current density, power density, output voltage, and continuous generation of renewable electrical energy with a sustainable approach
