    Mathematical modeling of a 500 We power module composed by a PEM fuel cell combined with a DC-DC enhanced potential output converter
    2012 - 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.

    Análise técnico econômica de unidades geradoras de energia distribuída
    2011 - MOTA, HENRIQUE de S.
    Neste trabalho analisou-se de forma técnica e econômica, diferentes unidades de geração elétrica. São elas: célula a combustível movida a hidrogênio, geração eólica, geração solar, geração hídrica, grupo moto gerador à diesel. Utiliza-se do software HOMER para simular o funcionamento das unidades geradoras. Ainda discute-se o tema energético, levanta-se os parâmetros de entrada, analisa-se as variáveis de sensibilidade e discute-se os resultados obtidos.
