One of the things to note about the ethanol/water issue. Water and ethanol are fully miscible; i.e., the blend is total and permanent under normal conditions. You can determine the "mix" by monitoring specific gravity and applying the appropriate formula to determine the "percentage" of water. There are other analytical methods available as well. While it is miscible, it is not hygroscopic in and of itself - water in alcohol is typically the result of condensation in the fuel cell and the aforementioned miscibility.
