My calculations continue to suggest that very little power is being generated by the cell. You are correct in assuming that others are calculating excess power while I do not is due to the monitor point that they are using, but recent measurements tend to add support to my method. The cells were cooled down and extra hydrogen added to bring the pressure approximately back to where it was during the calibration runs. When the systems were powered up again I determined roughly the same null result, but the other monitor points suggest that the significant excess power they were measuring has gone away.
I was not surprised by this result. The worst problem that my technique has to overcome is caused by variation in the density of the hydrogen gas. I believe this is due to the fact that lower density hydrogen leads to less heat being conducted from the hot wires. The wires rise in temperature as a result, leading to additional IR radiation. Some of the direct wire IR escapes capture in the glass envelop and is not detected. This causes the outer glass monitor, the one I rely upon, to cool down and I therefore calculate less power. The magnitude of the problem is enough to be a concern, but appears to generate much less error for me than for people using one of the internal sensors.
