A hydrogen evolution cell which on passage of an electric current liberates an amount of hydrogen proportional to an amount of current flowing through, includes an electrochemically oxidizable anode, a hydrogen cathode, an electrolyte and a casing surrounding the same, wherein the hydrogen cathode is associated structure of at least one pocket defining a hollow space or defines a hollow space in the presence of hydrogen overpressure or wherein the cathode forms such a pocket.

Hydrogen evolution cell having a cathode pocket

A method of producing a button cell having an anode including metal particles, including providing an anode mixture including as constituents metal particles, at least one binder, at least one conducting agent and, optionally, a gassing inhibitor, providing a button cell housing, introducing the mixture into the button cell housing, admixing the mixture with an electrolyte, and liquid-tight sealing of the housing, wherein the constituents of the mixture are contacted in the presence of water prior to introduction into the housing, and after the contacting the water is removed from the mixture at least partially.

Anode mixture, button cell with an anode comprising metal particles, and production thereof

A hydrogen evolution device that liberates hydrogen upon passage of an electric current, wherein an amount of liberated hydrogen is proportional to an amount of the current, includes at least one hydrogen evolution cell including an electrochemically oxidizable anode, a hydrogen cathode and an electrolyte, and at least one heating resistor thermally coupled to the hydrogen cathode directly or via a solid or liquid heat conductor.

Hydrogen evolution device and fuel cell system comprising the same

A button cell includes a positive electrode, a negative electrode and a separator arranged in a housing comprising a cell cup and a cell lid insulated from one another by a seal, wherein the negative electrode is tablet-shaped pressed body having a self-supporting structure.
