Abstract
Renewable energy generation is an innovative approach that uses the electrochemical properties of substances that can be used as fuels, for example, urine and in addition to mixed metal oxides for the generation of energy from fuel cells based on synthetic urine. In this study, energy generation was carried out in a synthetic urine sample, using ferrites of the CaFe2O4 and LaFeO3 type as anode. These materials act as sensors that react with the analytes present in the urine sample, producing a detectable electrical signal. In the study, a cell with two electrodes was used, one made of platinum (cathode) and another made of synthesized material (anode). The synthesized materials were prepared using a mixture of nitrates, and the synthetic urine sample, which was deposited on a paper microfluidic fuel cell design. Six assemblies were carried out and the results were satisfactory for the study.References Saputra, H. A. (2023). Electrochemical sensors: basic principles, engineering, and state of the art.
