This month the patent summaries have been made even briefer than they were before, in an effort to catch up most of the backlog of recently pubfished US and WO patents. It is encouraging that there is clearly so much research and development work going on in this very active area. We expect to retur

can be tailored to match gas flow patterns and gradients. Further refinements can be achieved by varying the print pattern across the cell, and by using multiple layers to control both the depth and structure of the layers within the pattern. The advantages of this gas diffusion electrode are higher
oxygen partial pressures 1.5, 10.2, 49.2, 100 and 286 Pa within the temperature range of 20-1050ยฐC were studied. Nickelate oxygen desorptionlsorption spectra when heating/cooling at constant rate demonstrated strong dependence of cation composition of the samples. Unlike La,,&, ,NiO, compounds, thos
