FUEL CELL ASSEMBLY FOR PORTABLE ELECTRONIC DEVICE AND INTERFACE, CONTROL, AND REGULATOR CIRCUIT FOR FUEL CELL POWERED ELECTRONIC DEVICE

摘要

A fuel cell assembly including a membrane electrodde assembly, an anode plate, a cathode plate, a removable fuel cartridge, and a fuel delivery system. The assembly includes an anode, a cathode, and a polymer electrolyte membrane having a fuel side and an oxygen side. The fuel cartridge includes an expandable fuel bladder for receicing liquid fuel, an expandable pressure member in contact with the bladder for maintaining a positivr pressure on the bladder, and a sealable exit port in fluid communication with the bladder. The fuel delivry system delivers fuel from the cartridge to the fuel side of the membrane. An Interface, Control, and Regulator Circuit for Fuel Cell Powered Electronic Device.
