A fluid regulating microvalve assembly for use to control fluid flow to a fluid consuming electrode, such as an oxygen reduction electrode, in an electrochemical cell is proposed. The microvalve assembly includes a stationary valve body having an aperture and microactuators movable from a first closed aperture position to at least a second position where fluid is able to pass through the microvalve body aperture. These microactuators control the movement of spring-like shape-retaining interior aperture covers, which covers can be belleville springs or flat springs. The fluid regulating microvalve assembly can utilize cell potential or a separate source. The latter assembly can be located outside or inside the cell housing, for example between a fluid inlet aperture and the fluid consuming electrode. Using a printing process to deposit at least one of the layers is proposed for making the multilayer microvalve assembly for a fluid depolarized battery.
