Patent
·
OSTI ID:7361823
A fuel cell is described comprising: 1. a generator cell having a fuel gas chamber, an oxidizing gas chamber, and an electrolyzing solution chamber; 2. a fuel gas circulating circuit; 3. an oxidizing gas circulating circuit; 4. an electrolyte circulating circuit; 5. a gas cooler located in the fuel gas circulating circuit beneath the generator cell; 6. a formed water tank located beneath the gas cooler and in fluid communication therewith, whereby moisture formed in said generating cell, carried by said fuel gas into said gas cooler, and condensed therein will drip by force of gravity into said formed water tank; 7. an electrolyzing solution tank; and 8. a clean water tank located above said electrolyzing solution tank and in fluid communication therewith, whereby clean water can be supplied by force of gravity from time to time to said electrolyzing solution tank from said clean water tank in order to control the concentration of the electrolytic solution therein. An improvement is described comprising: (a) means for sensing the level of electrolytic solution in said electrolyzing solution tank, and (b) means for opening the path of fluid communication between said electrolyzing solution tank and said clean water tank when the level of electrolytic solution in said electrolyzing solution tank is below a predetermined level and for closing the path of fluid communication between said electrolyzing solution tank and said clean water tank when the level of electrolytic solution in said electrolyzing solution tank is above the predetermined level.
