Fuel Cell Power Systems
ANSI/CSA America FC3-2004
American National Standard For Portable Fuel Cell Power Systems
1.1.1 This Standard applies to ac and dc type portable fuel cell power
systems, with a rated output voltage not exceeding 600 V, for
commercial, industrial, and residential indoor and outdoor use in
non-hazardous locations, in accordance with the Rules of the National
Electric Code, ANSI/NFPA 70.
1.1.2 This Standard does not apply to portable fuel cell power systems that are a. Permanently connected (stationary) to either fuel or electric supply; b. Designed to export power to the grid; c. Replacement fuel cell power units for appliances; or d. Fuel cell systems for propulsion.
1.1.3 Fuels considered within the scope of this standard are: a. Natural Gas; b. Liquefied Petroleum / Propane Gases; c. Liquid Alcohols e.g. Methanol, Ethanol; d. Gasoline; e. Diesel; f. Kerosene; g. Hydrogen; h. Chemical Hydrides; and i. Metallic.
1.1.4 The overall design of a portable fuel cell power system
anticipated by this standard shall form an assembly of integrated
systems, as necessary, intended to perform designated functions, as
follows: a. Fuel Processing System - meters and processes incoming fuel
supply for use within the portable fuel cell power system. b. Air
Processing System - meters, conditions, processes and may pressurize
(blowers or turbochargers) incoming air supply for use within the
portable fuel cell power system. c. Thermal Management System - provides
cooling and heat rejection to maintain thermal equilibrium within the
portable fuel cell power system and may provide for recovery of excess
heat and assist in heating the portable fuel cell power system during
startup. d. Electrical System - conditions output power of the fuel cell
to meet the specifications of the output system. e. Automatic Control
System - the assembly of sensors, actuators valves, switches, and
control logic components that maintains the portable fuel cell power
system control parameters within manufacturer specified limits without
manual intervention. f. Fuel Cell Module - an assembly of cells,
separators and cooling plates, manifolds and a supporting structure that
electrochemically converts fuel and oxidant to direct electrical
current, heat, water and other byproducts.
1.1.5 These requirements are not intended to prevent the design and
construction of a portable fuel cell power system not specifically
prescribed in this standard, provided that such
alternative has been considered in testing and listing the portable fuel
cell power system. In considering alternative designs or construction
the materials or methods used shall be evaluated as to their ability to
yield equivalent performance to that prescribed by this standard.
