The company that makes them is Central Semiconductors. The following snippet comes from: http://www.centralsemi.com/cld/index.aspx > A CURRENT LIMITING DIODE, CLD, also known as a "Current Regulating > Diode" or a "Constant Current Diode" performs quite a unique function. > Similar to a zener diode, which regulates voltage at a particular > current, the CLD limits or regulates current over a wide voltage range. > > Available in a wide range of voltage and current ratings, and offered > in a variety of leaded and surface mount package styles, the CLD > provides an alternative to conventional design techniques for > controlling current, especially when reliability and component density > are prime considerations. Basically, it's a small, cylindrical body about a 1/4" (6mm) long and about a third that in diameter, with wires coming out each end. You hook it up in series with your generating cell. They come in sizes rated from about .22 to 4.7 milliamps and they can handle supply voltages up to about 100V, I think. If it's backwards, with respect to the battery polarity, it'll block current completely. In the other direction, it will allow no more than a certain amount of current specified by the part's current rating. On a practical level, you want to have a digital milliamp meter connected in series so you can see what's going on. If you don't own one already, they're available cheaply from places like Harbor Freight Tools, Radio Shack, or many other vendors of electronic equipment. When you start, the current will be well below the rating of the diode, until enough silver gets into the water to let more current flow. It will slowly climb and, after a long enough wait, it'll limit at or close to the diode current limit value. The diodes are available from Mouser Electronics: http://www.mouser.com If you type the three terms "curr reg diodes" into their site search box, it will bring up a listing of all that are available. Unfortunately, more sensible terms like "current regulator diodes" don't work! <sigh> They're not expensive. Let us know if you need further help. Be well, Mike D.
