Catalytic activity of the anode material YSZ-cerium dioxide was tested for possible use in fuel-cell reactors, as a high-active component but is sensitive to hydrogen (Nakagawa et al. 2001). 

In a ceramic electrochemical reactor oxygen activation is physically separate from substrate activation. Activation of dioxygen occurs at a cathodic surface, oxygen traverses the electrolyte as oxide ions, the ions react with a substrate on the anodic face, and the electrons return to complete the circuit. Two types of electrochemical membrane reactors are under study which differ in the route by which the electrons travel from anode to cathode these are illustrated schematically in Figure 1. In the shorted fuel cell reactor the electrons return through an external circuit, from which electrical power can be extracted. Electroceramic membranes allow the electrons to make their way from anode to cathode via electrically conductive phases within the membrane proper. 

Tubular fuel cell reactors can be prepared easily by applying anode and cathode layers to the opposing faces of dense yttria stabilized zirconia (YSZ) tubes. The cathode and... 

We describe here an experimental approach to design PEM fuel cell reactors where the complexities of macroscopic design parameters are chosen to obtain data in the least ambiguous form, not to optimize the overall power output. The fuel cell designs presented here can be used with virtually any membrane-electrode assembly these are fuel cell test stations. The fuel cell reactors described here can be thought of as building blocks for more complex fuel cells designs.
