Ventilation components for injection molding tools for thermoplastics, elastomers, silicones and thermosetting polymers, made up of metallic and/or non-metallic powder material by a laser sintering process

Detecting potential differences in e.g. fuel cell stacks, batteries or series electrolysis circuits, employs automatically-controlled measurement position selection switch

Combining two or more fuel cell units, comprises using one unit which is permanently active and which supplies heat to another

Contact plate for low-temperature fuel cell, has inlet channels, outlet channels and flow field enclosed by groove, where cross section of channels is broader in flow direction, and side walls of channels obtain contour

Operating arrangement for fixing metallic workpieces when coating surfaces, preferably of car bodies, is made from mechanically stable base bodies, preferably based on natural material and mineral or organic adhesives and/or binding agents

Bipolar plate manufacturing method for e.g. hydrogen cell, involves inserting temperature-resistant sealing into groove before manufacturing process, where rod is provided in outer region of plate and leaves groove in plate after assembling

Operating unit e.g. plastic holder, for holding motor vehicle-body part, has contact and interference sections that are elastically implemented, where unit is implemented in certain distance to fixation of body parts

Fuel e.g. alkaline earth metal, cell e.g. phosphoric acid fuel cell, for e.g. military application, has anode that is formed as container, in which fuel is provided, where container is covered by electrolyte layer consisting of separators

Fuel cell arrangement for road, air and sea vehicles comprises control unit which equalizes electrical load of vehicle at rest and self-ignition of starter or traction battery

Fuel cell stack contacting device, has contact pins assembled on circuit boards, which are arranged as sides of rhombuses and stand parallel to one another, such that boards are aligned correctly to contact stack arrangements of electrodes
