T/CEEIA 670-2023 Fuel cell low conductivity coolant technical requirements

Scope

Scope: This document specifies the technical requirements, test methods, and inspection rules for low-conductivity coolant fluids used in fuel cells. This document applies to proton exchange membrane fuel cells and power generation systems with liquid cooling, and the materials are limited to aluminum-magnesium alloys, copper-based metals, stainless steel, titanium, brazed sheets, and other suitable metals and non-metallic materials. Note 1: This document does not apply to proton exchange membrane fuel cells and power generation systems that require the installation of specific ion-removing circulation equipment. Note 2: Heat utilization systems such as direct-cooled lithium batteries that require low-conductivity media can refer to this document for use.
