Abstract
A cold start device for an exothermic hydrogen consumer such as a fuel cell, as well as a method for operating an exothermic hydrogen consumer with a metal hydride storage system. An exothermic hydrogen consumer such as a fuel cell with an efficient cold start device which can be brought into operation rapidly and. does not require a pressure tank is provided. The cold start device is available for an unlimited number of start-up procedures. At least one starter tank is filled with a metal hydride which has an equilibrium pressure for desorption of at least 100 kPa at a temperature of −40° C., as well as at least one operating tank which is filled with at least one metal hydride, which has an equilibrium pressure of <100 kPa at temperatures of <0° C., and wherein the starter tank is incorporated into the operating tank.
