A process for producing a hydrogen storage means. Separate layers comprising a hydrogen-storing material and a heat-conducting material are introduced into a press mold. The separate layers of the hydrogen-storing material and the heat-conducting material are compressed together to generate a sandwich structure. The heat-conducting material, on use of the sandwich structure as hydrogen storage means, assumes the task of conducting heat.
