Hydrogen generator having liquid delivery member

摘要

A hydrogen generator is provided for generating hydrogen gas for a fuel cell stack. The hydrogen generator includes container, and a first reactant storage area configured to contain a liquid first reactant. The hydrogen generator also includes a reaction area and a solid second reactant within the reaction area, and a hydrogen outlet. The hydrogen generator further includes a flexible liquid delivery member extending into the reaction area and configured to deliver liquid reactant from the first reactant storage area to the reaction area. The flexible liquid delivery member includes a flexible portion that flexes to allow the delivery member to move with the solid second reactant as the second reactant is consumed.

主权项

1. A hydrogen generator comprising:
a container; a first reactant storage area configured to contain a liquid comprising a first reactant; a reaction area within the container; a solid comprising a second reactant within the reaction area; a hydrogen outlet; and a liquid delivery member extending into the reaction area and configured to deliver the liquid from the first reactant storage area to the reaction area, wherein the liquid delivery member comprises a liquid distribution portion and a flexible portion, more flexible than the liquid distribution portion, that flexes to allow the liquid distribution portion to move with the solid as the second reactant is consumed; wherein the liquid delivery member extends from an exhaust nozzle that is in communication with the hydrogen outlet; and, wherein the liquid delivery member comprises a first tube delivery portion coupled to a liquid inlet port, a second liquid distribution portion, and a U-shaped connector connecting the first and second portions, wherein at least one of the first portion and the U-shaped connector is flexible.
