Artigo IPEN-doc 22701 Mathematical modeling of a 500 We power module composed by a PEM fuel cell combined with a DC-DC enhanced potential output converter2012 - SENNA, ROQUE M. de; LINARDI, MARCELO; CASSIANO, DOUGLAS A.; SANTOS, IVAN; MOTA, HENRIQUE de S.; JERONIMO, ROSIMEIRE A.This work presents the development of a mathematical modeling of a 500 We PEMFC fuel cell stack (MCC500) system combined with a dc-dc enhanced potential output converter. The MCC500 was developed at IPEN (Nuclear and Energy Research Institute) and the company Electrocell, using only Brazilian technology. Mathematical developments and modeling have been performed, relying on experimental data collected at IPEN laboratory. The first step was to prepare an electrical system (pre-design) for the proposed model, which included the MCC500 parameters, like: membrane ohmic resistance, activation resistance, electric double layer capacitance, open circuit potential, as well as DC-DC converter parameters, like: inductor and transistor switching frequency. Using the obtained parameters and a linear differential equation system with some mathematical manipulations, an electrical system model was determined. Simulations experiments demonstrated that the system was very stable. This toll contribution showed to be very important to generate useful potential for practical purposes, increasing the overall system electrical efficiency.Resumo IPEN-doc 18584 Experimental data and mathematical model of a 500 we PEMFC fuel cell stack combined to a DC-DC step-up converter with enhanced power output2012 - SENNA, R.M. de; LINARDI, M.; CUNHA, E.F. da; CASSIANO, D.A.; MOTA, H. de S.; JERONIMO, R.A.
