Fuel Cell Power Systems for Industrial Electric Trucks -
Part 1: Safety
1 Scope
This document specifies the safety requirements for the fuel cell power systems for industrial
electric trucks.
This document applies to industrial electric trucks using gaseous hydrogen fuel cell power
systems and direct methanol fuel cell power systems.
This document applies to fuel cell-driven industrial trucks used for handling, ejecting, pulling,
lifting, stacking or piling up various goods, such as: forklifts and single-bucket loaders, etc.
This document applies to the fuel cell power systems defined in 3.8 and Figure 1.
This document applies to DC fuel cell power systems with a rated output voltage not exceeding
150 V for indoor and outdoor use.
For the fuel cell power systems involved in this document, the fuel source container is
permanently attached to the industrial trucks or the fuel cell power systems.
Within the scope of this document, the following fuels are considered:
---gaseous hydrogen;
---methanol.
Within the scope of this document, the following contents are not included:
---removable fuel source containers;
---hybrid industrial trucks containing internal combustion engines;
---fuel cell power systems with reformers;
---fuel cell power systems for operation in potentially explosive atmospheres;
---fuel storage systems using liquid hydrogen.

3 Terms and Definitions
The following terms and definitions are applicable to this document.
3.1 Abnormal Operation
Abnormal operation means the fuel cell power system operates in the event of failure of any
electrical or control component, or in any of the failure modes identified by the failure mode
and effect analysis (FMEA) procedure, excluding accidental rupture or damage to flammable
liquids, vapor and / or gas containers.
3.2 Bonding
Bonding refers to a permanent connection to metal parts to form a positively conductive path
that provides electrical connection between non-current-carrying metal parts and is capable of
conducting any fault currents that may occur.
NOTE: it is applicable to the connection inside the fuel cell power system, and between the fuel
cell power system and the vehicle, and does not involve measures like grounding the
vehicle itself through the grounding terminal or tires. Any active modes, such a...
