NFPA 110 is going through its first substantial change in decades and the change will affect those who typically were not subject to NFPA 110's requirements. The different uses of fuel cells have increased as the cells became a viable power source option. One such use is as an emergency power source. The National Electrical Code(NEC) has permitted fuel cells as an emergency source since 2005. NFPA 99, Health Care Facility Code added fuel cells as an acceptable emergency source in 2012. The scope of NFPA 110 is the performance of emergency and standby power systems providing an alternate source of emergency electrical power to loads in buildings and facilities in the event that the primary power source fails.
Currently, there are no NFPA 110 requirements addressing fuel cells for that application.
The performance of an emergency power system is critical for life safety. With the increased interest is utilizing fuel cells, general installation requirements for fuel cells are inadequate just as general requirements for a generator were inadequate. There needs to be specific requirements to address issues to help ensure proper fuel cell function during an emergency. To that end, the NFPA 110 Technical Committee is seeking public and industry comments for the next edition of the standard. The intent is to provide performance requirements similar to those for generators.
Much work is being conducted to have the requirements fleshed out for the Second Draft meeting. The Technical Committee has drafted Committee Input No. 9 (CI-9) to solicit comments on the performance requirements specific to a fuel cell used as an emergency system. Please review CI-9 through the online portal.
