GB/T 31037.1-2014: Fuel cell power system used for industrial lift truck applications -- Part 1: Safety

This Part of GB/T 31037 specifies the safety requirements and safety precautions involved in the construction, identification and performance tests of the fuel cell power system used for industrial lift truck applications. Fuel cell power systems that power electric industrial lift trucks for indoor or outdoor use include fuel cell power systems (referred to as power systems) and energy storage modules. An energy storage module refers to an electrical energy storage device that is used to start a power system, or to help or supplement a fuel cell power system to power internal or external loads. It consists of a lead-acid battery, a nickel-metal hydride battery, a lithium-ion battery, a super capacitor, or other energy storage modules with corresponding functions. This Part covers only the safety requirements of the fuel cell power system and does not include energy storage modules.

Fuel cell power system used for industrial
lift truck applications -- Part 1. Safety
1 Scope
1.1 Overview
This Part of GB/T 31037 specifies the safety requirements and safety
precautions involved in the construction, identification and performance tests of the fuel cell power system used for industrial lift truck applications. Fuel cell power systems that power electric industrial lift trucks for indoor or outdoor use include fuel cell power systems (referred to as power systems) and energy storage modules. An energy storage module refers to an electrical energy storage device that is used to start a power system, or to help or supplement a fuel cell power system to power internal or external loads. It consists of a lead-acid battery, a nickel-metal hydride battery, a lithium-ion battery, a super capacitor, or other energy storage modules with corresponding functions. This Part covers only the safety requirements of the fuel cell power system and does not include energy storage modules.
The industrial lift trucks involved in this Part include. counterbalanced fork lift truck, reach truck, straddle truck, pallet-stacking truck, platform truck, truck with elevatable operation position, side-loading truck, rough terrain truck, lateral stacking truck (both sides), lateral and front stacking truck, stacking high-lift straddle carrier, pallet truck, platform and stillage truck, non-stacking low-lift straddle carrier, and order picking truck.
This Part is applicable to proton exchange membrane (PEM) fuel cell power systems that use gaseous hydrogen as the fuel and air as the oxidant.
Hydrogen storage devices suitable for use in this Part include.
?€? fixed or replaceable;
?€? refillable or disposable;
?€? integrated or installed on power systems or industrial lift trucks.
This Part only considers dangerous situations that may cause injury to people, objects or the environment outside the fuel cell power system, and proposes safety requirements for such dangerous situations, excluding the safety used to filter and regulate the pressure of the oxidant (air) input to the power system, then deliver oxidant (air) to the fuel cell module.
?€? Thermal management system. It includes, but is not limited to radiators and associated fans, piping, circulating fluid pumps, valves, sensor devices, cooling fluid storage and replenishment tanks, etc., which can be used to keep the power system operating within the manufacturer specified
operating temperature range by heating or cooling or heat removal.
?€? Humidifying system. A device for humidifying fuel and oxidant (air) to increase relative humidity.
?€? Water treatment system. It includes, but is not limited to piping, circulating water pumps, valves, sensor devices, water storage and replenishment
tanks, etc. When water generated by the power system is used for
humidifying fuel or oxidant or other uses, the particles and metal ions that are harmful to the power system shall be removed.
?€? Control system. It consists of sensor devices, circuits, actuators, control devices, and software programs that are necessary for regulation and
monitoring, so that the power system?€?s operating parameters are able to be kept within the manufacturer?€?s given limits without human intervention, thus ensuring the normal operation of the power system.
?€? Power regulating system. It includes, but is not limited to DC / DC or DC / AC, circuits, etc. The output power of the fuel cell stack will, by regulating current and voltage according to the requirements for the power required for the internal device of the power system and the external output power, provide the power output that meets the requirements of use.
?€? Ventilation system. A system that achieves air exchange inside and outside the power system through forced or natural means.
?€? Fuel cell power system. It consists of all or part of the components in the schematic diagram for the boundary of the power system, and is combined with an energy storage module to form a fuel cell dynamic system.
According to its different structures, it can be divided into two types. all-in- one and integrated.
??? All-in-one system. All the components of the power system are loaded
into one shell as an integral whole; the display and control interface or function buttons can be installed in the place where the operator can
conveniently operate according to the actual situation.
??? Integrated system. All the components of the power system are
dispersedly installed on an industrial lift truck in accordance with the structural space and the center of gravity of the industrial lift truck. However, all the components are connected together through circuits
