中国のSongsheng Jiang博士が過剰熱発生実験に成功した件の追加情報が出ていますので紹介します。
まず、熱電対で計測したグラフが詳細に見える資料が以下に公開されました。

Figure 6 data for New Result on Anomalous Heat Production in Hydrogen-loaded Metals at high Temperature
By Songsheng Jiang, of the China Institute of Atomic Energy
この実験では以下のような装置を用いています。外側にヒーターがあり、熱電対T1が最もヒータに近い温度を測っています。中心に燃料が置いてあり、その燃料の外側の温度を熱電対T2が測っています。燃料に最も近かった熱電対T3は途中で故障しました。
実験の計測データのグラフが上記のPDF資料のP3(5月4日~7日)とP4(5月7日~8日)に掲載されています。これを見ると5月5日の12時くらいまでは、赤(T1)が緑(T2)を上回っていて、予想される普通の状態ですが、15時くらいに青(T3)が壊れたと思われるあたりで緑(T2)の温度が急上昇し、赤(T1)よりも高い温度になってしまったのが見て取れます。
また、E-Cat Worldに以下のようなQAが載っており、様々な疑問に対してJiang博士が直截に回答してくれています。

以下、簡単に要点をメモしておきます。
1 – Can you provide information about nickel powder and LiAlH4 used? For example, the manufacturer, purity, particle size, surface morphology, etc.
The nickel powder and LiAlH4 was all commercial products, produced in Beijing and Tianjin respectively. The size of metal nickel powder is from a few microns to tens of microns. We not used carbonyl nickel powder in this experiment. The purity is higher than 99.9%. Surface morphology is unknown.
使用したニッケルパウダーのLiAlH4も市販されているもの。ニッケルパウダーの大きさは2~3ミクロンから数十ミクロン。
2 – Do you have any SEM (scanning electron microscope) images of the nickel, LiAlH4, the mixed fuel, and the ash or used fuel?
We not do any SEM images in this experiment. We don’t think it is important for judging excess heat production. The surface structure may have changes at high temperature and loading hydrogen into nickel, but it cannot give a direct evidence of excess heat production.
SEMイメージは撮っていない。過剰熱発生を判定するのに重要ではないと思っている。
3 – How did you process the nickel and LiAlH4 before placing it in the reactor? Can you detail how the fuel was loaded into the nickel reactor cell? Was the powder tightly packed or loose?
Original LiAlH4 is in a sealed metal bag, and the bag is in a sealed metal can. When we prepare the fuel, open the can and bag, then take out a certain amount of LiAlH4 by small chemical spoon and then weight nickel powder and LiAlH4 separately. The both were mixed homogeneously by the spoon on a clear paper. Then the mixed powders was put into the fuel cell and compressed by spoon tightly. For safety, the person working at the nickel and LiAlH4 powders was wearing masks and gloves
元のLiAlH4は金属の袋に入っている。ケミカルなスプーンで取り出して、ニッケルパウダーと紙の上で拡販。そのミックスパウダーを燃料セルの中に入れてスプーンで押しこむ。
5 – Do you think having low pressure in the cell is important in producing excess heat? If so, why?
I do not think having low pressure in the cell is important in producing excess heat. After first hydrogen-loaded process, excess heat has no significant correlation with pressure in our experiment (see fig. 6, yellow line).
セルの圧力を低くするのは重要だとは思っていない。
6 – How much free space was in the reactor chamber compared to the fuel volume?
The total space volume of the reactor chamber was about 220 ml and the fuel volume was less than 35 ml.
リアクターチャンバーの容積は220ml、燃料の容積は35ml以下。
7 – A hydrogen tank is mentioned in the report. Did you add hydrogen to the reactor from the tank?
Yes, the hydrogen bottle was used for sometime, for example, increasing pressure as test

8 – The report states that the reactor operated in self sustain mode for 20 minutes. However, the graph on page 11 seems to show the voltage (blue line) did not go to zero until 10:50 which would make the period of self sustain only about 10 minutes. Can you explain this?
The report does not show how much self sustaining time around 10:50 on 8 May. The self sustain mode for 20 minutes is in the first self sustain period on 5 May. This self sustaining process is not shown in Fig. 7a and 7b.
最初の20分間のセルフサステインモードは、5月5日の最初のセルフサステイン期間に現れている。
9 – When you examined the nickel cell afterwards, what condition was it and the fuel in? Was the nickel cell melted?
After experiment, the fuels were melted in the cell, but nickel box was not melted, it was well.
実験の後、燃料はセルの中で溶けていた。しかし、ニッケルボックスは溶けずに良好な状態。
10 – Can you provide the raw data from this experiment?
Fig.7a is an automatic plot of data logger (recorder), in other words, it was raw data. The excel data can be exported for making other figures. I do not think it is necessary to provide raw data information.
図7a自体がローデータだと考えている。
11 – Did you control the experiment manually, or did you use any kind of controller?
We control the experiment manually right now.
実験は手作業で制御している。
12 – T1 is always constant in Fig 7b, but it would seem that because of heat transfer from T2 to T1, the T1 cannot be constant. Could T1 be damaged?
T1 was not constant in the whole experiment (see Fig. 6, red and green curves ). T1 temperature may change while tuning input power. The constant T1 temperature may be correlated with very low pressure (much lower than 1 atmospheric pressure in the chamber). In this case, thermal conductivity in the chamber was very low. Also, the heat capacity of fuel cell was much small than the reaction chamber. The low thermal conductivity and large different heat capacity between a small fuel cell and large reaction chamber may make heat transfer from core cell to the T1 very slowly and lose a lot in the way, no reason to doubt T1 damaged.
コアセルかT1への熱伝導は非常にゆっくりしている(?)
13. On the cooling down … T2 is far below T1. But they should go together to an equilibrium due to the setup of the experiment. If there is no added heat, delta T1-T2 must lead to 0. But T2 is below T1 at ~11:30. Could T2 be damaged?
T1 was near the heater, T2 was on the cell wall, both were separated by reaction chamber. When no excess heat source, the T2 temperature is lower than T1. If enough excess heat is produced, T2 may be higher than T1 ( also see Fig. 6, red and green curves).
T1はヒータのそばにある。T2はセル壁の上にある。両者はリアクションチャンバーで隔てられている。過剰熱がないなら、T2はT1より温度が低い。過剰熱があればT2はT1より温度が高くなるかもしれない。
14. What kind of calibration was done for this experiment?
We was used the method similar to Focardi et al work in 1998 to calibrate factor of W/0C, it is about 1.5-2.5.
Focardi博士らと同じ手法でキャリブレーションした。
16. – What are your plans for your next experiment?
We have not made final plan how to do the next experiment, hope to improve the temperature measurement.
また次の実験計画は立てていない。温度計測を改善したいと思っている。
