A plate member for a cell stack, a cell stack assembly, a method of forming a plate member for a cell stack and a method of assembling a cell stack may be provided, and the plate member includes a channel sheet with at least one peak and one trough for forming fluid flow channels; two alignment parts, each alignment part including a main body and one or more alignment members or holes, the main body having a through hole provided within the main body; and wherein the alignment part is capable of aligning the channel sheet parallel to a plane of the main body and the alignment member is capable of aligning the alignment member to another corresponding alignment member along an axis passing through the alignment member; and further wherein the channel sheet is disposed between the two alignment parts.

Plate member for a cell stack

The present invention relates to a solid fuel, a system and a method for generating hydrogen. The solid fuel comprises sodium borohydride, catalyst loaded fibres and a binder, wherein the catalyst loaded fibres and the binder form a scaffold structure within which the sodium borohydride is positioned. The system comprises a fuel cartridge containing the solid fuel of the present invention for generating hydrogen gas, a reactor configured to house the fuel cartridge, a tank for storing water, a pump and a liquid conduit for conveying water from the tank to the fuel cartridge housed within the reactor to induce a hydrolysis reaction of the solid fuel contained in the fuel cartridge and a controller for regulating flow of the water.

Hydrogen generating system

A gas generator and a method of generating a gas are provided. A gas generator includes a cartridge having a solid reactant and a liquid reactant distributor provided therein, and a liquid reactant supply in fluid communication with the liquid reactant distributor. The liquid reactant supply is configured to provide a liquid reactant under pressure to the liquid reactant distributor. The liquid reactant distributor comprises a plurality of normally closed holes configured to open at a predetermined fluid pressure to disperse the liquid reactant for reaction with the solid reactant in the cartridge.
