Description

Fuel cells are energy converters that, unlike heat engines, convert chemical energy directly into electrical energy. Heat is generated as a by-product during this process
The main component of it is a polymer-membrane fuel cell which is operated in combined heat and power generation. The system is supplied with high-purity hydrogen from a pressure vessel on the anode side and with oxygen from the ambient air on the cathode side. The fuel cell is operated either current-regulated or voltage-regulated via an integrated electronic load. The setpoint of the electronic load allows a precise adjustment of all operating points and a very accurate recording of characteristics. The technically usable thermal energy is dissipated to the environment via a cooling circuit and can be accounted for via the integrated instrumentation. The water accruing during operation is collected in a water separator. In the fuel cell’s dead-end mode the accruing water is disposed of via a configurable purge valve for hydrogen. The system is operated via a PC.
