Fighter's Quantum Power Cell Replication

Hello. I also started doing some experiments with PEG cell. I use pure PEG8000, it's easy to get and cheap. It has just longer molecules than 4450. For now I am using pure PEG without other added substances to see how it behaves. I started with aluminum and copper electrodes, but then I thought it would be best to eliminate as many variables as possible, so I made a test cell with pure PEG and both electrodes with carbon (cleaned and fired carbon rods from the battery). This way I am sure that there is no galvanic reaction. I would like to ask a few things.
1) aren't you worried that if you add water to the mixture, some of it will stay inside and never evaporate? Yes, you can then bake the whole thing, but you can use melted PEG straight away. That's how I do it for now, then I don't have to wait days for it to dry and i can be sure that there is no water.
2) Why do you think that the multimeter will show you true information about the internal resistance? A multimeter cannot measure the resistance of something that produces its own voltage (unless they have a special function for measuring the internal resistance of batteries). I calculated the internal resistance using the no-load voltage of the cell and the short-circuit current (the short-circuit voltage is so low that it is unmeasurable with my equipment, it will show 0), and I also measured the current flowing through the cell with a connected voltage of 30V from the source. Both methods gave me a similar result of around 1.3Mohm of PEGcell internal resistance. I would like to discuss a few more things and share and compare measurement results if you are interested..
