Linear temperature model for fuel cell simulators

Alternative sources of energy has been the subject of study by researchers, is the need to master the technology or by the growing demand for renewable energy sources. Many studies have turned to survey models for simulation of fuel cells as an aid in the manufacture of electronic circuits for integration and use of energy generated by this kind of power source, due to the high cost of these equipments and used fuel (hydrogen). This work hereby presents a simulation model that includes the effect of the variation of temperature with the requested cell current. Such a model has been developed from tests on a fuel cell of 1,2kW - Nexa Power Module, using the identification by the method of least squares with pseudo-random binary signals and optimization tools.
