The heat exchange cell is of a configuration similar to that of the fuel cell and, in the stack, should directly adjoin the fuel cell battery, so that the spent cooling air is utilized to heat a medium without an intermediate line.

Abstract: According to the present invention network devices that can be controlled via a speech unit included in the network can send a device-document describing its functionality and its speech interface to said speech unit. The speech unit combines those documents to a general document that forms the basis to translate recognized user-commands into user-network-commands to control the connected network-devices. A device-document comprises at least the vocabulary and the commands associated therewith for the corresponding device. Furtheron, pronunciation, grammar for word sequences, rules for speech understanding and dialog can be contained in such documents as well as the same information for multiple languages or information for dynamic dialogs in speech understanding. It is possible that one device contains several documents and dynamically sends them to the speech unit in case they are needed.

Abstract: Home networks low-cost digital interfaces are introduced that integrate entertainment, communication and computing electronics into consumer multimedia. Normally, these are low-cost, easy to use systems, since they allow the user to remove or add any kind of network devices with the bus being active. To improve the user interface a speech unit (2) is proposed that enables all devices (11) connected to the bus system (31) to be controlled by a single speech recognition device. The properties of this device, e.g. the vocabulary can be dynamically and actively extended by the consumer devices (11) connected to the bus system (31). The proposed technology is independent from a specific bus standard, e.g. the IEEE 1394 standard, and is well-suited for all kinds of wired wireless home networks. The speech unit (2) receives data and messages from the device. The speech unit (2) recognizes speaker-dependent commands. A Speech synthesizer synthesizes messages.

Abstract: A fuel cell battery is described which has a liquid cooling. The fuel cell battery has a primary cooling circuit and a secondary cooling circuit with a heat exchanger connected between them. The heat exchanger is structurally integrated into the battery, so that the length of the primary cooling circuit is minimized and the primary cooling circuit requires no external lines, i.e. lines that lead out of the battery.

A fuel cell stack is preferably located at the radiator of the vehicle and the relative wind directly cools the individual fuel cells.
