Abstract

A multi-stage shift reactor includes a vessel having an inner chamber configured to contain a first shift catalyst, the first shift catalyst configured to receive anode exhaust gas form a fuel cell and to output a first shifted gas, and an outer chamber annularly disposed about the inner chamber and configured to contain a second shift catalyst, the second shift catalyst configured to receive the first shifted gas and output a second shifted gas. The shift reactor further includes a water injection port downstream from the inner chamber and packing between the water injection port and the outer chamber, the packing configured to prevent liquid water from passing therethrough.

Direct methanol fuel cell and system

Patent Wilson, Mahlon S [Los Alamos, NM]

A fuel cell having an anode and a cathode and a polymer electrolyte membrane located between anode and cathode gas diffusion backings uses a methanol vapor fuel supply. A permeable polymer electrolyte membrane having a permeability effective to sustain a carbon dioxide flux equivalent to at least 10 mA/cm.sup.2 provides for removal of carbon dioxide produced at the anode by reaction of methanol with water. Another aspect of the present invention includes a superabsorpent polymer material placed in proximity to the anode gas diffusion backing to hold liquid methanol or liquid methanol solution without wetting the anode gas diffusion backingmore » « less

Fuel cell using a hydrogen generation system

Patent Dentinger, Paul M [Sunol, CA]; Crowell, Jeffrey A. W. [Castro Valley, CA]

A system is described for storing and generating hydrogen and, in particular, a system for storing and generating hydrogen for use in an H.sub.2/O.sub.2 fuel cell. The hydrogen storage system uses beta particles from a beta particle emitting material to degrade an organic polymer material to release substantially pure hydrogen. In a preferred embodiment of the invention, beta particles from .sup.63Ni are used to release hydrogen from linear polyethylene.
