Water-balance Assessment in a Reformer/Fuel-cell System

Abstract. In PEM fuel cells pure hydrogen is used as a fuel. Due to its low density, the density of its stored energy is low, too. One of the possible solutions to the problem is production of hydrogen from the energy-reach material, e.g. methanol. Conversion of methanol to hydrogen is made with reformer in a steam reforming process in which besides methanol there is also water needed. On the o...

Spiral Methanol to Hydrogen Micro-Reformer for Fuel Cell Applications

Eagle Strategy Based Maximum Power Point Tracker for Fuel Cell System

A bunch of factors including the limited fossil resources and rising of fossil fuel price have been causes moving to create the new structure that is based on providing energy security, and protect the environment. One of the alternatives is the fuel cell (FC). Maximum power point tracker has an important role to increase the efficiency of the FC systems. One of the difficulties in maximum powe...

Decentralized Robust Power System Stabilizer Design

This paper suggests a method for designing PSS to damp multi-machine power system oscillations.  The method is based on robust control theory. First, the conventional method for designing robust controller in LMI framework is illustrated. Then, the suggested method is given, in which, a PID output feedback controller is tuned using the LMI approach. Mostly, the classical methods are used t...

A Compact Reformer for Portable Fuel Cells

A compact reformer to generate hydrogen for portable fuel cell applications is presented. This reformer is a conventional type single-path tubular reactor packed with granular catalyst particles in which steam reforming and catalytic partial oxidation reactions take place in series using a mixture of methanol and water as a feed. The novel feature of this reformer is in the interlacing of the f...
