Fuel cell technologies - Part 3-400: Stationary fuel cell power systems - Small stationary fuel cell power system with combined heat and power output - Edition 1.0
 N 62282-3-400

Annotation

This part of IEC 62282 applies to small stationary fuel cell power systems serving as a heating appliance providing both electric power and useful heat with or without a supplementary heat generator providing peak load function.

This standard applies to fuel cell power systems that are intended to be permanently connected to the electrical system of the customer (end user). Direct connection to the mains (parallel operation) is also within the scope of this standard.

NOTE 1 Parallel operation is subject to the permission of the local electric power supply utility.

This standard is limited to gas and liquid fuelled fuel cell CHP appliances that have a heat input based on lower heating value of less than or equal to 70 kW. For some regional applications, the output electric power is limited. Specific limitations are given in Clause C.1 for Japan.

This standard applies to systems as shown in Figure 1.

One is a system where both stationary fuel cell power system and supplementary heat generator are installed in one enclosure without any partition.

This standard does not have to apply to the supplementary heat generator of systems where the stationary fuel cell power system and the supplementary heat generator are not built in one enclosure, and whose ducts are not common (that is, each appliance has its own dedicated duct system).

This standard applies to systems intended for operation on the following supplied input fuels:
