Microwave Assisted Pyrolysis of Waste Tires: Study and Design of Half-Cells SOFCs with Low Environmental Impact

In order to establish novel application for the solid residual from microwave assisted pyrolysis (MAP) of waste tires we have evaluated the potential electrocatalytic efficiency of a collection of char from MAP in Oxygen Reduction Reaction (ORR). The basic idea comes from the consideration that the presence of different metals together with a high carbon in char object of study, produces synergic catalytic effects and are mandatory requirements for ORR on PEMFCs. Recent progresses on metals of transitions from Map as promotion of LSCF are discussed focusing on two main aspects, the different synthesis approaches used and the effects of metal promotion on structural properties, oxygen vacancies content and cathodic performances. Associated with increased catalytic, the novelty of the work lies in the fact that the char obtained from microwave assisted pyrolysis of waste tires represent a low-cost and ”green” source of metals needed for the IT-SOFCs cathode.
