Abstract: A hydrogen generator includes a container having a gas outlet that is configured to contain a soluble chemical fuel that reacts with a catalyst to generate hydrogen. A control cylinder is attached to the container and comprises a piston configured to travel axially within the control cylinder, a pole attached to the piston and extending into the container, a catalyst holder provided within the container and connected to the pole, resilient means biasing the catalyst holder towards a bottom of the container, and a gas inlet port. A gas flow line is in fluid communication with the gas outlet and has a first end in fluid communication with the gas inlet port, a second end configured to feed hydrogen to a hydrogen-consuming device, and a two-way valve provided to allow fluid communication between the first and second ends of the gas flow line to be selectably established or cut off.

Abstract: A composite catalyst is provided. The composite catalyst includes a first catalytic material incorporated with a second catalytic material, wherein the first catalytic material comprises carbon doped with (i) nitrogen and (ii) at least one non-precious transition metal, and wherein the second catalytic material comprises a carbon-based supporting material incorporated with platinum nanoparticles. A method of producing the composite catalyst is also provided. The method includes providing a mixture comprising the first catalytic material and the second catalytic material, and subjecting the mixture to a size reduction step. The first catalytic material and a method of producing the first catalytic material are disclosed herein.

Abstract: Disclosed herein is a composite material formed from an inorganic mesoporous, or mesoporous-like, material that is dispersed throughout a polymeric matrix formed by a crosslinked polymer that has acidic- or basic-residues and which may also optionally have further acidic- or basic-residues grafted onto the inorganic mesoporous material. The resulting composite material may be used to remove acidic or basic impurities from a gas in need thereof and can be easily regenerated.
