Reduction of the Premature Aging of PEM Fuel Cell - Battery systems by Implementing an Advanced Hybrid Control System Based on Double PID, Neural Network Load Predicting Algorithm and Optimal Battery Sizing Algorithm.
Proton Exchange Membrane Fuel Cell (PEM-FC) is a technology that is associated with three main challenges that can be summarised as cost, reliability and lifetime. Current global research in PEM-FC focuses on reducing the use of expensive precious materials to reduce costs. Research is also …

Control of balance of plant components for solid oxide fuel cell systems with sensitivity to carbon formation
Solid oxide fuel cell systems have the potential to provide efficient, low greenhouse gas emitting power without the availability problems of both wind and solar energy. SOFC systems operate at high temperatures (600 C) in order to reduce ionic transport losses through a ceramic electrolyte. The …

The Integration of State Space into the Dynamic Synthesis/Design and Operational/Control Optimization of a PEMFC System
… is a secondary task to be solved by system and control engineers once the synthesis/design is fixed. This thesis considers the system dynamics in the process of developing the system using a set of transient thermodynamic, kinetic, and geometric as well as physical and cost models developed and …

Dynamic subdivided relative humidity model of a polymer electrolyte membrane fuel cell
The development of a control-oriented dynamic relative humidity model for a polymer electrolyte membrane (PEM) fuel cell stack is presented. This model is integrated with a first law based thermal model, which tracks energy flow within four defined control volumes in the fuel cell; the cathode …
