Hydrogen generating fuel cell cartridges
First Claim
1. A gas-generating apparatus comprising a reaction chamber, where a hydrogen gas is produced from a reaction between a metal hydride and a liquid reactant, and a hydrogen separating member disposed within the reaction chamber and connected to a coupler of the reaction chamber,wherein the hydrogen separating member comprises a gas permeable, liquid impermeable membrane covering a porous member, wherein the porous member is connected to the coupler and wherein the hydrogen gas permeates through the hydrogen separating member through the porous member and to the coupler.

Abstract
A gas-generating apparatus includes a cartridge including a reservoir having a first reactant and a reaction chamber, and a receiver that can include a flow control device. The receiver is adapted to receive the cartridge and to transport the first reactant to the reaction chamber after connection with the cartridge. The flow control device is adapted to stop the transport of reactant when the pressure in the reaction chamber reaches a predetermined pressure.
