—Hybridization with high specific energy-storage devices such as supercapacitors (SCs) has important advantages in fuel-cell (FC)-based systems. This paper presents an approach for the design and analysis of FC hybrid systems (FCHSs) oriented to automotive applications. The FCHS is considered to be the most attractive long-term option for propulsion of(More)
In this work, a model based fault diagnosis methodology for PEM fuel cell systems is presented. The methodology is based on computing residuals, indicators that are obtained comparing measured inputs and outputs with analytical relationships, which are obtained by system modelling. The innovation of this methodology is based on the characterization of the(More)
The transient behavior of a Fuel Processor System to produce Hydrogen from bio-ethanol with high performance, coupled with a Proton Exchange Membrane Fuel Cell is modeled. The Ethanol Processor is based on a previous steady state design, optimized to work with maximum efficiency around 10 kW of rated power. From the dynamic rigorous model, a linearized(More)
In this paper, fault-tolerant MPC control of PEM fuel cells is addressed. MPC is a suitable control methodology to control fuel cell systems because of their multivariable and complex behaviour. Additionally, MPC is one of the control methodologies that can introduce more easily fault-tolerance. However, the problem of including actuator fault-tolerance in(More)
Polymer Electrolyte Membrane Fuel Cells (PEMFC) are efficient devices that convert the chemical energy of the reactants in electricity. In this type of fuel cells, the performance of the air supply system is fundamental to improve their efficiency. An accurate mathematical model representing the air filling dynamics for a wide range of operating points is(More)
The sizing and energy management for fuel cell hybrid vehicles with supercapacitors is addressed in this work. The hybridization with high specific energy elements significantly improves the advantages of fuel cells, specially in automotive applications where the load fluctuates considerably. The sizing is based on conductibility requirements while the(More)
This paper addresses the control of an experimental PEM fuel cell system. The fuel cell station is composed by an ElectroChem<sup>&#x00AE;</sup> 7-cell stack with Nafion 115<sup>&#x00AE;</sup> membrane electrodes assemblies (MEAs) and the auxiliary equipment. The control problem is focussed on the air supply in the cathode. The main objectives are to(More)
This work focuses on the preliminary study of an integrated hybrid system to produce hydrogen from bio-ethanol using solar energy as an auxiliary power source. It is analyzed for mobile applications, particularly, for a system that can use an on-board bio-ethanol processor. The solar power is used for promoting the reforming reaction for hydrogen production(More)
