Abstract
A variable pressure passive regenerative fuel cell system is provided wherein both the fuel cell and electrolyzer are designed to operate under variable pressure conditions.
Claims5
A method for controlling process water used in a variable pressure passive regenerative fuel cell system including a fuel cell and an electrolyzer comprising:
- (a) configuring the fuel cell system to position a water tank intermediate a fuel cell and an electrolyzer such that the fuel cell is above the water tank and the electrolyzer below the water tank whereby water produced by the fuel cell is gravity feed to the water tank and oxygen produced at the electrolyzer's anode ascends into the water tank;
- (b) further configuring the fuel cell system to include means communicating with said water storage tank for supplying water to an anode cavity of an anode component of said fuel cell;
- and
- (c) providing a fiber packed column structure for controlling the flow of water to said main water tank, and fuel cell during fuel cell system operation.
