Contact element for electrical connection of e.g. rechargeable battery, has plated-through holes electrically connecting contact layer with conductor structure and passed through one of layers

摘要

The contact element has guide way structures (5) for feeding gasiform and/or fluid form reactant and/or for discharging the reactant to/from an electrical conducting contact layer (1) and/or an electrode (2). An electrical conductor structure (6) is arranged between individual layers (4a-4f) for receiving electrical power from an electrochemical cell (3), where the layers are made of low-temperature or high-temperature co-fired ceramics. Plated-through holes electrically connect the contact layer with the electrical conductor structure, and are passed through one of the layers.
