Fuel cell device e.g. oxide-ceramic high temperature fuel cell device, has electrode formed such that electrochemical activity of electrode is increased along main flow direction to increase gas conversion at electrode

摘要

The device has a supply device (56) comprising a flow path (68) that is oriented with respect to a main flow direction (62) transverse to a connection direction (28). The supply device is formed such that a surface application of a boundary face (64) is increased along the main flow direction of the flow path and/or an electrode (22) i.e. anode, is formed such that an electrochemical activity of the electrode is increased along the main flow direction to increase a gas conversion related to a surface element of the boundary face at the electrode along the main flow direction. An independent claim is also included for a method for manufacturing or operating a fuel cell device.
