Found a section in, of all places, volume 2 of Stodola and Loewenstein's _Steam and Gas Turbines_ that interests us. Section 214 talks about "gas batteries" made up of high temperature fuel cells with fused electrolytes and sintered iron-based electrodes running on a mixture of CO, H2 and inert gases at high temperature (1650 F and up). Based on Swiss and German patents of the nineteen teens. Lots of technical problems that might easily be solved today. Sounds like a good scheme for integration with a gazogène. I can post a scan to any appropriate spot. Is there a Files area for this list? Anybody know where I can find copies of old Swiss and German patents.
