produced from coal, coke, or oil, or by reforming
of natural or liquefied petroleum gases, (Gas

Proposed IFGC Approach Chapter 7 scope to
include all gaseous H2 and gaseous H2 fuel
applications

• - In all non-integrated technologies generating
  and using hydrogen for stationary and automotive
  PEM fuel cell applications, hydrogen is the only
  fuel, other fuels (NG, LPG, CO) are present in
  trace amounts.
• - Expand Chapter 7 scope to cover all
  non-transportation gaseous hydrogen fuel systems
  (hydrogen fuel generation, refueling stations,
  fuel cell power systems using hydrogen fuel)
• - Requirements specific to mixtures having more
  than 95-percent H2 by volume should make this
  explicit each time they appear.

Proposed IFGC Approach Chapter 7 for all H2 fuel
applications

• HYDROGEN-GENERATING APPLIANCE. A self-contained
• package or factory-matched packages of integrated
  systems
• for generating gaseous hydrogen and gaseous
  hydrogen fuel.
• Hydrogen- generating appliances utilize
  electrolysis, reformation,
• chemical or other processes to generate hydrogen.
• GASEOUS HYDROGEN SYSTEM. An assembly of piping,
• devices and apparatus designed to generate,
  store, contain, distribute
• or transport gaseous hydrogen and gaseous
  hydrogen fuel .
• Gaseous hydrogen systems consist of items such as
• compressed gas containers, reactors and
  appurtenances,
• including pressure regulators, pressure
• relief devices, manifolds, pumps, compressors and
• interconnecting piping and tubing and controls.

• Definitions
• GASEOUS HYDROGEN FUEL. A nontoxic combustible gas
  mixture containing at least 30-percent gaseous
  hydrogen by volume and having not more than
  5-percent of other combustible gases by volume
  and not more than 1-percent oxygen by volume.
• GASEOUS HYDROGEN. A hydrogen gas of Type I as per
  CGA G-5.3. (NOTE CGA G-5.3 Commodity
  specification for hydrogen.)
