Abstract: The invention provides 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.

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: The invention relates to a method for large scale manufacturing of polymeric micro fuel cells using a metallic mold. The method includes creating a Gaussian-shaped channel on a first substrate using a laser; sputtering a metallic seed layer over the first substrate using a first metal; electroplating a second metal over the seed layer to create a negative mold; releasing the negative mold from the first substrate; fabricating a plurality of second substrates, each having a Gaussian-shaped channel, and using the negative mold to fabricate multiple fuel cells. The method provides lower cost and greater flexibility as compared with conventional ablation and etching processes of manufacturing of polymeric micro fuel cells.
