4 Comparative results (Nov. 13)

the Graphs below show the behaviour of DIY cells #5 & #2 compared to two control experiments: one with a NiMH AAA cell (with medium charge), one with a 'sister' cell to Cell #5 (ie. both cells constructed at the same time and with the same materials & method)

  in each experiment the cells are continuously loaded: Cell #5, cellstack #2 and the NiMH cell both have similar pulsed LED loads, Cell #5b has a constant passive load (6M6R resistor in parallel with 200uF capacitor) with an equivalent power-draw to the Cell #5 experiment

 all graphs use the same
voltage scale for easier comparison; they clearly show that the DIY cells with pulsed loads are gradually increasing in charge whilst in the two control tests the cell voltage is gradually discharging
