ABSTRACT:
This invention contemplates using semiconductor microactuators as small valves in combination with electric appliances powered by fluid depolarized electrochemical batteries, especially zinc-air cells, or in combination with fluid depolarized electrochemical batteries themselves, all to regulate fluid flow into the batteries. The purpose is to prevent degradation of the batteries when idle, yet permit fluid flow when operating and only when operating. The valves are proposed to be modified to use them as movement devices and valves, using the traditional moving part of the semiconduictor microactuator to move a slide. To increase the area available for fluid flow, the invention proposes to use grids of aperatures for structural integrity, which when the grids are aligned, allows for fluid flow, and when "unaligned" in the normally closed position, block fluid flow. Pressure relief characteristics, corrosion protection, control circuitry, circulation means, and other advantages and methods are also claimed.
