Modeling and simulation of PEM fuel cell – power converter system
Parasitic capacitances of Proton Exchange Membrane (PEM) fuel cell are causing electrical effects resulting with change of dynamic behavior of fuel cell stack output voltage. This paper shows PEM fuel cell dynamic model with capability of easy integration of humidity, temperature and pressures dynamics, as well as their control. Fuel cell stack dynamic model was linked with boost converter aver...
متن کاملModeling and Simulation of a Modern Pem Fuel Cell System
Recent trends and advances in hydrogen/air Proton Exchange Membrane Fuel Cells (PEMFC) are incorporated into a dynamic control oriented model. This type of model is important for development of control systems for PEMFC powered transportation where unpredictable and widely varying changes in power demand can be expected. Self humidification and low pressure operation are the two major changes t...
متن کاملModeling and Identification of a Pem Fuel Cell Humidification System
A theoretical model of a humidifier of Proton Exchange Membrane (PEM) fuel cell systems is developed and analyzed first in this paper. The model shows that there exists a strong nonlinearity in the system. Then, the system is identified using a wavelet networks method. To avoid the curse-of-dimensionality problem, a class of wavelet networks proposed by Billings is employed. The experimental da...

متن کاملDevelopment and Simulation of a PEM Fuel Cell model for Prediction of Water Content and Power Generation
The proton exchange membrane (PEMFC) fuel cell represents the energy of the future, in parallel with hydrogen. However, this technology must meet many technical challenges related to performance and durability before being sold on a large scale. It is well known that these challenges are closely linked to water management. This paper develops and implements a model of PEM fuel for simulation to...
