Title:
TUBULAR ELECTROCHEMICAL DEVICES WITH LATERAL FUEL APERTURES FOR INCREASING ACTIVE SURFACE AREA
Document Type and Number:
WIPO Patent Application WO2001071841
Kind Code:
A3
Abstract:
An electrochemical device is designed to conduct a process gas both horizontally and vertically through the electrochemical device, such that problems resulting from mal-distribution of the process gas are substantially eliminated. The structure of the electrochemical device includes a stacked assembly of planar sheets (44) of parallel, integrally connected tubes (24), wherein the tubes conduct a first process gas horizontally throughout the electrochemical device, passages (26) defined between adjacent stacked sheets conduct a second process gas horizontally throughout the electrochemical device, and novel apertures (42) formed at the connection between adjacent tubes within the sheets conduct the second process gas vertically throughout the electrochemical device.
