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.
Claims8
A variable pressure passive regenerative fuel cell system comprising:
- a) a fuel cell including an anode for receiving hydrogen gas and a cathode for receiving oxygen gas;
- b) an electrolyzer for electrolyzing water to produce pure hydrogen and pure oxygen;
- c) means to store said hydrogen and oxygen from said electrolyzer:.
- d) a water storage tank communicating with said fuel cell and said electrolyzer;
- e) a fiber packed column having a structural housing wrapped with electrical resistance heater wire and wherein said fiber packed column is communicating with said water storage tank for supplying water to an anode cavity of said anode of said fuel cell;
- f) means to supply water to said electrolyzer for producing hydrogen and oxygen;
- g) means for supplying hydrogen gas and oxygen gas to said fuel cell;
- and
- h) means for controlling the supply of water to said water tank.
