(US5366823-A)      The fuel cell has an electrolyte between an anode and a cathode, and a compression pad for compensating for component dimensional variations at pressures exceeding 1500 psig comprising an elastic metal that returns to its original thickness after it has been compressed and having sufficient porosity to attain an elastic strain of 3-40% at about 2500 psig. The porosity is 20-60% and the metal is Cu, Ni, stainless steel, or their alloys or mixts.    ADVANTAGE -   Operating pressure range exceeds 6000 psig, and even up to 10000 psig, while maintaining a conductive path, uniform contact pressure, fluid tight seals, and preventing movement of the electrolyte.    (JP7509756-W)      Cell having anode, electrolyte and cathode includes a porous metal compression pad for compensating component dimensional variations at pressures above 1500, pref. 1500-10000 psig. The metal has sufficient porosity of pref 15-85, esp. 20-60% to attain an elastic strain of 3-40% at 2500 psig. Pref. the metal is pref. Cu, Ni, stainless steel or an alloy of these.    USE/ADVANTAGE -   Use is in a fuel cell (stack) or electrolysis cell stack (claimed). Compression pad permits operating pressures of up to 10000 psig (or more) while maintaining a conductive path; uniform contact pressure and fluid tight seals and preventing movement of the electrolyte.    (US5466354-A)      An improved electrolysis cell having an anode electrode, a cathode electrode, and an electrolyte disposed therebetween, wherein the improvement comprises: a compression pad for compensating for component dimensional variations at pressures exceeding about 1,500 psig, the compression pad comprising: a metal having sufficient porosity to attain an elastic strain between about 3% and about 40% at about 2,500 psig.    (EP674811-B1)      Cell having anode, electrolyte and cathode includes a porous metal compression pad for compensating component dimensional variations at pressures above 1500, pref. 1500-10000 psig. The metal has sufficient porosity of pref 15-85, esp. 20-60% to attain an elastic strain of 3-40% at 2500 psig. Pref. the metal is pref. Cu, Ni, stainless steel or an alloy of these.    USE/ADVANTAGE -   Use is in a fuel cell (stack) or electrolysis cell stack (claimed). Compression pad permits operating pressures of up to 10000 psig (or more) while maintaining a conductive path; uniform contact pressure and fluid tight seals and preventing movement of the electrolyte.
