Spiral Methanol to Hydrogen Micro-Reformer for Fuel Cell Applications

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...

Temperature control of open-cathode PEM fuel cells

Proper temperature control of Proton Exchange Membrane Fuel Cells is a crucial factor for optimizing fuel cell performance. This paper describes a model-based characterization of the equilibrium points of an open-cathode fuel cell system. Phase plane analysis of the nonlinear model versus a linearized model around different points of operation shows the potential of approximating the nonlinear ...

High-temperature Fuel Cells

The molten carbonate fuel cell operates at approximately 650 °C (1200 °F). The high operating temperature is needed to achieve sufficient conductivity of the carbonate electrolyte, yet allow the use of low-cost metal cell components. A benefit associated with this high temperature is that noble metal catalysts are not required for the cell electrochemical oxidation and reduction processes. Molt...
