β¦ Synopsis
The kinetics of methanol-steam reformation were studied in an idealized tube reactor and a non-ideal internal reforming fuel cell. Methanol conversion in the IRFC was significantly less than in an ideal plug flow reactor, but for higher current densities the IRFC requires less catalyst.

## Abstract In this paper we report the results obtained for interβmatrix synthesis (IMS) and characterization of monometallic and bimetallic polymerβstabilized metal nanoparticles (PSMNPs). The IMS procedure is based on the use of appropriately functionalized polymeric membranes as nanoreactors, w
