In Europe, validation/test bench facilities for fuel cells must be certified. What certification is expected in the U.S?

In the U.S., there is no specific national requirement for fuel cell test equipment to be certified. There may be requirements from the local authority having jurisdiction (AHJ). Local building codes will likely point to compliance with NFPA 2/55 for the hydrogen and other gas supply systems, ASME Boiler and Pressure Vessel Code for vessels, ASME B31 piping codes for piping, and National Electric Code for electrical. A conversation with the local authorities early in the planning process to determine what is required will be helpful. Consultation with a design firm for laboratories and factories may also be helpful. It may be possible to show that many test station components already certified to EU standards can meet U.S. requirements with some cross-reference work. Alternately, the AHJ may accept the CE Declaration of Conformity.
