Patent number: 7923140Abstract: 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. The microvalve assembly includes a stationary valve body having an aperture and a microactuator movable from a first position where the microvalve body aperture is closed to fluid flow to at least a second position where fluid is able to pass through the microvalve body aperture. The fluid regulating microvalve assembly can utilize cell potential or a separate source to open and close the microvalve. The fluid regulating microvalve assembly can be located outside the cell housing or inside the cell housing, for example between one or more fluid inlet apertures and the fluid consuming electrode. The invention includes a method of making a multilayer microvalve assembly, particularly one for use in a fluid depolarized battery, using a printing process to deposit at least one of the layers.Type: GrantFiled: July 8, 2010Date of Patent: April 12, 2011Inventor: Brooke Schumm, Jr.

Publication number: 20110045326Abstract: In a battery module, having a housing, at least one battery, which is disposed in the housing, at least one inlet opening for introducing a cooling fluid into the housing, and at least one outlet opening for conducting the cooling fluid out of the housing. According to the invention, compressed cooling fluid can be supplied to the at least one inlet opening using a compressor. A reduction of the cooling performance because of heating of the compressed cooling fluid is to be at least partially avoided. Furthermore, the design effort is to be low and the battery module is to be cost-effective to produce. The invention solves a problem in that the cooling fluid can be cooled by a cooling apparatus.Type: ApplicationFiled: January 23, 2009Publication date: February 24, 2011Inventors: Stephan Leuthner, Philipp Kohlrausch
