Abstract or Summary
  • A Mixed Reactant Single Chamber (MRSC) Fuel Cell is a relatively recent concept in the field of fuel cell engineering originally developed in the late 1950’s. Typical fuel cells have separated reactants (a separated fuel and oxidizer) that react on their usually non-selective electro-catalytic materials. A mixed reactant fuel cell uses a mixed reactant source (a fuel and oxidant mixed gas). The use of selective catalytic materials in the MRSC fuel cell eliminates the need for high cost filtering and separation of the reactant gases. The intended application of an MRSC fuel cell is to exploit the energy of a decaying radioactive power source that produces, via water radiolysis, a mixture of hydrogen and oxygen gasses through the decomposition of water. This mixed reactant source, can power an MRSC fuel cell to produce power on a small scale for an extended period of time. Described within, water electrolysis is used to simulate the process of water radiolysis, in turn providing a mixed reactant source and powering the MRSC fuel cell. In a closed and controlled environment test, the electrolysis of a 0.5 Mol KOH electrolyte solution in combination with a platinized platinum mesh anode and porous silver cathode yielded a max power density for the MRSC fuel cell of 129 µW cm-2.
