Hydrogen Cools Well,but Safety is Crucial

摘要

Operating an electric power generator produces large amounts of heat that must be removed to maintain efficiency. Air, water and oil have all been used for cooling. But hydrogen's low density, high specific heat and thermal conductivity make it a superior coolant for this application. Plus, it's abundant and therefore relatively inexpensive.rnThe problem is, hydrogen can be dangerous. In its pure state, hydrogen is fine, but a mixture of air and hydrogen can be explosive.
