Please confirm the power output is 2W/m^2. Not sure where he got those numbers, but I suspect he mis-interpreted them. They talk about power outputs in the ranges of 0.2 watts per cm² to 0.5 watts per cm² (here's the link to the article) .... gri.org Bear in mind that the above quoted results sound like they were achieved under "laboratory test" conditions and that there is no evidence that they were able to achieve similar results in a working prototype with the 10x10 cm. size that GLE used for their tests, nor in fact is there any evidence that they have any working prototype whatsoever. For comparison purposes, using the 40 watt figure (800 watts/20 cells) for a 10x10 cm. cell, equates to 0.4 watts per cm² for the GLE cell.

Dingo, just as a follow-up to my previous post ... I agreed with your calculations and arrived at a figure of 0.4 watts per cm² for the GLE cell. But in fact, if you go their web-site at ... 207.148.154.93 you'll see that they have already (April 1999) announced results with power outputs even higher than the figure mentioned above. Actual output varies with the temperature the cell is run at (the higher the temperature the higher the output). They report, for instance, 550 milliwatts (or 0.55 watts) per cm² at a temperature of 700°C. and as high as 915 milliwatts per cm² at temperatures of 900°C.

No Problem in your calculations. The problem is I can't type right. That figure should have read 2W/cm^2. By your calculations, GLE is getting around .4W/cm^2, approx. 5x less than what is speculated as the upper limit by the GRI group. However, if memory serves correctly, this same group claims to get around .5w/cm^2 as a practical output from (their own?) cell. From this, we can see that both groups of researchers (GLE and GRI) are getting comparable power levels from the SOFC, confirming the GLE claims to be realistic and within the bounds of current technology. I see this as a confirmation of GLE's integrity in the reporting of their SOFC testing. Well done on your observation, Dingo. There's nothing wrong with your calculations, and I applaud your ability to apply Physics 101 to the real world of technological development. Regards, Rocky
