Design and Investigation of Honeycomb End Plates for PEM Fuel Cells

In this article a new structure of PEM fuel cell end plate is presented. The new structure is known as a honeycomb sandwich panel. Several properties of the presented structure, such as mechanical and thermal behavior, as well as its advantages and disadvantages are introduced. The aim of this paper is to reduce the weight of the while maintaining a better compression force on the PEM fuel cell...

Fault-Tolerant MPC Control of PEM Fuel Cells

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 the control loops of these systems has...

Fuel Processors for PEM Fuel Cells

Objectives • Demonstrate high performance desulfurizer, catalyst, micro-reactor and microcombustor/ microvaporizer concepts that will enable production of compact fuel processors for proton exchange membrane (PEM) fuel cells • Design, fabricate and evaluate a 1-kWe fuel-flexible fuel processor during the first 36 months (one of the fuels capable of being reformed will be EPA Phase II reformulat...
