Fuel cell power plants with an output greater than 50 kW should be installed according to which NFPA Standard?

The correct answer is NFPA 853, which is specifically developed to provide guidelines for the installation of fuel cell power plants with an output greater than 50 kW. This standard addresses the unique safety considerations associated with fuel cells, including aspects such as hydrogen safety, fire protection measures, and system design parameters that ensure reliable operation.

By following NFPA 853, professionals can ensure that these larger power plants are not only compliant with safety regulations but also designed to minimize risks associated with the storage and use of hydrogen and other fuels typically involved in fuel cell systems. The standard serves as a critical resource for developers and engineers working on fuel cell installations to implement best practices and maintain safety standards in their projects.
