The reaction route (RR) graph approach recently developed by us for complex, non-linear kinetic mechanisms is applied to the hydrogen oxidation and evolution reactions. A corresponding RR graph isâ€¦ (More)

In this paper a new model for porous electrodes in molten-carbonate fuel cells (MCFC) is presented. The model is based on an averaging technique commonly used in porous-media problems. Importantâ€¦ (More)

This article presents a vector space formulation for constructing reaction routes (reaction pathways) and Kirchhoff graphs (reaction route graphs) for reaction networks. Specific examples, manyâ€¦ (More)

The fundamental relationship between matrices over the rational numbers and a newly defined type of graph, a Kirchhoff graph, is discussed. For a given matrix, a Kirchhoff graph for that matrixâ€¦ (More)

A detailed mathematical analysis is performed to understand the anode potential oscillations observed experimentally in a proton exchange membrane fuel cell ~PEMFC! with H2 /CO feed ~Ref. 9!.â€¦ (More)

This work studies mathematical issues associated with steady-state modelling of diffusion-reaction-conduction processes in an electrolyte wedge (meniscus corner) of a current-producing porousâ€¦ (More)

In order to overcome loss in optical fibers, experimentalists are interested in employing parametric amplifiers using four-wave mixing. Upon linearizing the nonlinear SchrÃ¶dinger equation typicallyâ€¦ (More)

The US military has a need to find detailed maps of a specific region that is current to within a few hours. The current technology for this involves Unmanned Aerial Vehicles (UAV), which areâ€¦ (More)

Component potential modelling based on solid-oxide electrochemistry is used to study a single-particle configuration where a hemispherical LSM particle sits on a YSZ electrolyte half-space. Theâ€¦ (More)
