There are many nickel types of plate available. While doing research on the nano particle project I ran into the information. Most plates put into the very large industrial electrolizers are Nickel 200. The oil companies use them to make hho. They then seperate the H from the O and somehow use the H for some part of the oil production. They are now finding this process of nano coated nickel 200 plates to not only be effecient but last for years with no maintnance. The question that I can not find the answer for is what the differences in effeciency are between stainless and nickel. This is used mostly by big oil and they do not release effeciency numbers.
