QCF12 high current density fuel cell fixture

QCF12High current density fuel cell fixture

⇒ Working current density up to 5 A/cm2

⇒ The cooling layer is in direct contact with the flow field

⇒ Cold start and deep freezing

⇒ qualityguarantee

⇒ Production can be repeatedsex

⇒ Improved productivity

The latest version of QuickCONNECT testing unit has significant improvements in temperature management; The qCF high-efficiency liquid cooling system can be used for high current density operations, and battery heating is the most critical issue. In collaboration with Fraunhofer ISE, the liquid cooling layer is placed as close to the flow channel as possible, even in contact with the graphite flow channel bipolar plate, to more effectively remove the generated heat from the battery; The temperature difference between the cathode gas outlet and the coolant is very small, at 5A/cm²It can achieve around 1K at 80 ℃; All the advantages of the quick connect design are retained, such as adjustable contact pressure on the active area, self-adjusting single-stage piston, components that do not require disassembly tools, independence of sample thickness, etc., which can ensure easy operation and the highest reproducibility of results.

Cooling fixture design concept:

◎Determine the maximum power density by determining the optimal contact pressure on the effective area

◎The continuously adjustable contact pressure ensures complete repeatability of the testing conditions

◎Ensure independent thickness of internal fuel cell components through self-adjusting pistons and special seals

◎Quickly and easily clamp/assemble fixture components without the need for precise exchange of tools and internal components of the fixture

◎Specially designed to meet the strong demands of special quality assurance and laboratory environment

◎The membrane required for battery replacement does not require hose connectors or wires

◎Quick release and automatic plug save time
