Abstract
A fuel cell uses hydrogen as a fuel and oxygen as an oxidant and a hollow member is partially located in an anode chamber, partially located in a cathode chamber and partially located in a water collecting chamber. The hollow member contains a non electrolyte aqueous solution, eg sucrose solution. The hollow member is formed from a semi-permeable membrane which allows water to permeate therethrough but prevents hydrogen, oxygen and the solute, eg sucrose permeating therethrough. Water transported through a solid polymer electrolyte from the anode chamber to the cathode chamber and water produced in the cathode chamber permeates through the semi-permeable membrane into the hollow member by osmosis. Water in the hollow member permeates through the semi-permeable membrane into the anode chamber and dryer regions of the cathode chamber by osmosis. Water in the hollow member permeates through the semi-permeable membrane into the water collecting chamber.
