This paper presents a PEM fuel cell dynamic modeling, to be employed with electronic circuit simulator software - PSIM. Simulations of the proposed model for the fuel-cell, supplying a step-up DC-DC converter are presented. Comparisons with existing models are also made. Practical results are presented in this paper for a Ballard 1.2kW Nexa Power Module for theoretical-experimental comparisons.
Power flow control strategy is very important for fuel cell (FC) vehicle (FCV) with energy storage (ES) to improve the system dynamic performance and increase system efficiency. The design of power flow strategy will also affect the size of ES and life cycles of FC and ES. Traditionally, power flow control strategies are studied either using hardware power train test bed or using pure software (PC...
In this paper a DC power plant for base transceiver station power supply is investigated. The supply system employs clean alternative energy sources, namely photovoltaic (PV) modules, wind turbines, a fuel cell as backup generator and a storage battery bank. A detailed description is made and experimental data are shown of a prototype system where the PV modules are directly connected to the DC bus...
This paper consists on the integration of a polymer electrolyte fuel cell (PEFC) stack in an embedded system specifically in the transport applications. The fuel cell is characterised by a low-voltage high-current electrical power device. Therefore, it is obvious that a dedicated power interface is necessary to adapt and fix voltage and current levels accordingly to the application requirements. In...
A triple-half-bridge (THB) multiple-input bidirectional dc-dc converter was proposed recently to interface battery and ultracapacitor. This paper presents a power distribution control to coordinate the power partitioning among fuel cell, battery, and ultracapacitor when this THB converter is applied to the fuel cell vehicle system. A particular goal is to obtain both a peaking load control and state...
