Abstract
A power generator including one or more fuel cells, a fuel chamber enclosing a hydrogen generating fuel, and one or more slideable cylindrical valves in contact with the fuel chamber. The one or more valves include an inner cylindrical component with first perforations, and a slideable cylindrical component with second perforations and having a plurality of separated flexible sections. The valves are useful in controlling the flow of hydrogen into the anode portion of the fuel cell.
Claims20
An electrical power generator, comprising:
- one or more fuel cells;
- a fuel chamber, enclosing a hydrogen generating fuel;
- and
- one or more valves, at least partially surrounding the fuel chamber;
- wherein the one or more valves includes concentric inner and outer components:
- a fixed component with first perforations;
- and
- a slideable component with second perforations, having a plurality of separated flexible sections;
- wherein the flexible sections are supported at the top and bottom, wherein the separation of the flexible sections is formed by slits that are in a longitudinal direction, and wherein the flexible sections are thicker on the sides adjacent to the slits to improve structural rigidity.
