“…The various advantages and disadvantages of both the HBFC and DMFC systems have been discussed by Berger et al,previously (7,20,21). Some progress has also been recorded in another kind of regenerative fuel cell in applying aqueous KOH absorbed in asbestos in a solid electrolyte (11,12).…”

“…The temperature limitation characteristic of organic polymeric ion exchange membrane systems remains up to the present time. Efforts have been made to alleviate such shortcomings by such innovations as the Hydrogen-Bromine Fuel Cell (HBFC) and the Dual Membrane Fuel Cell (DMFC) (7,21). In the fdrmer, a sulfonated polystyrene cation-exchange membrane separates the anode from the catholyte compartment (liquid phase) comprised of an aqueous solution of bromine and HBr.…”

Sintered zirconium phosphate membranes containing zeolites have significant water absorptive capacities over a temperature range of from ambient to 150°C. This feature makes them sufficiently conductive for fuel cell applications over this temperature range. Such membranes have transverse strengths of 5000 to 6000 psi. They readily gain and lose water vapor in a reversible manner while maintaining good stability. This accounts for promising results obtained to date for regenerative hydrogen--oxygen fuel cells using this membrane. In addition to presenting regenerative hydrogen-oxygen fuel cell data, water absorptivity and conductivity data are given and interpreted in terms of membrane composition and structure.'"phe earliest reported use of zirconium phosphate membranes as a solid A electrolyte for hydrogen-oxygen fuel cells dates back to 1961 (9,10, IS). Astropower Laboratory has been investigating the electrochemical behavior of modified zirconium phosphate structures from both a fundamental as well as a developmental aspect. Significantly, a comprehensive investigation of composition and fabrication techniques, as they are related to membrane strength, conductivity, and hydrolytic stability, has led to deriving useful solid electrolyte structures. This is evidenced by successful hydrogen-oxygen fuel cell tests over the temperature range of 25° to 148°C. (6).Most characteristic of these membranes is an incorporated zeolite component serving a water-balancing function by virtue of its high affinity for water and low rate of desorption. In this manner, the conductivity of the membrane is maintained at a suitable level over wide temperature 17
