Title:
A PROTON EXCHANGE MEMBRANE FUEL CELL BATTERY
Document Type and Number:
WIPO Patent Application WO/2003/083986
Kind Code:
A1
Abstract:
The present invention relates to a proton exchange membrane fuel cell battery, the fuel cell battery includes at least two kinds of reactive material supply cavities and a membrane electrode, said two kinds of reactive material supply cavities positioned alternately, the membrane electrode positioned therebetween. Reactive material flow field formed of any one of the reactive material supply cavity positioned between every two adjacent membrane electrodes is shared by said two adjacent membrane electrodes. A collector plate is positioned on two sides of the membrane electrode, electromotive force generated by every membrane electrode are connected in series through electric connection of the collector plate. In the present invention, reaction cavity configuration is used, in this configuration, non-double electrodes use same reactive material together. In this way, cost of the fuel battery is decreased, power-volume ratio is increased, this fuel battery is prone to manufacture and it can be used conveniently. Moreover, voltage generated by every membrane electrode according to the present invention are connected in series outside of the battery, so the problem, bad performance of single battery cell influences performance of the whole cell battery, can be avoided.
