Asymtek, a Nordson company and leader in dispensing and jetting technologies, will feature its Mass Flow Calibration (MFC) jet dispensing of catalyst ink on fuel cell membranes technology at the 4th International Hydrogen and Fuel Cell Expo, in late February at Tokyo Big Sight in Tokyo.

Asymtek’s coating and dispensing technologies apply catalyst inks onto membranes in electrode assemblies (MEA) of proton exchange /direct methanol fuel cells. One of the difficulties in coating a membrane is to control the metal loading, yet this control is easily done with Asymtek’s integrated balance scale. The amount of ink is software controlled by entering the weight needed for the MEA into Asymtek’s Fluidmove for Windows XP software.

The company will present several types of dispensing and coating technologies for increased flexibility, with any of these coating technologies capable of automatically calibrating itself. The discrete dot dispensing technology offered by Asymtek uses the DispenseJet DJ-9000 valve to create specific patterns with high edge definition and exact placement of these expensive inks. The DispenseJet DJ- 2200 non-contact jet coats in tight spaces and can dispense lines just 3mm wide. The pulse spray coats both large and small areas, while Asymtek offers the combination of these technologies to give the customer a highly flexible, high throughput coating system.

Asymtek, considered to be a world leader in automated fluid dispensing, conformal coating, and jetting technologies, designs and manufactures a full line of dispensing and coating systems, supported by a global applications and service network. The company continues to offer advanced applications for a range of industries including semiconductor packaging, printed circuit board assembly, LEDs, flat panel display assembly, automotive, medical/biotech product assembly, fuel cell, photovoltaic, and other precision assembly processes.
