This Japanese Industrial Standard specifies the matters required for the general
safety code, performance maintenance control, etc. for the stationary and portable small
polymer electrolyte fuel cell power systems (hereafter referred to as "fuel cell systems")
such as its structure, material, function, installation criteria, marking and sign, and
operation manual.
This Standard is applied to the fuel cell system satisfying the following items.
a) Kind of fuel cell Polymer electrolyte fuel cell
b) Output Rated transmission output of less than 10 kW
c) Output mode Grid-connected operation, grid-independent operation or indepen-
dent operation of dc output or ac output of 220 V or less
d) Raw fuel Gaseous fuel (city gas, liquefied petroleum gas, etc.), liquid fuel (kero-
sene etc.) or hydrogen
e) Operating pressure Maximum allowable working pressure of the portion
through which fuel gas passes of less than 0.1 MPa
f) System configuration Stationary and portable dedicated power generation sys-
tem or cogeneration system stored in a package (except a micro fuel cell)
