Abstract

One way to reduce the cost of making PEM Fuel Cells is to reduce the thickness of the layer. The layer is located between GDL and PEMFC electrode. This layer, to refute the electrode, is expressed with thickness, porosity, pore diameter, active surface area. In this working paper, the results of the thin film research results have been mapped and the results of the tests are to determine the characteristics of the thin layer thickness reduction. The mapping and analysis results were obtained at thicknesses ranging from 250 µm. In testing the thickness of 250 µm can still be reduced by a spray machine of 145 µm with a carbon density of about 2 mg cm-2 , but PEMFC's performance is smaller than the achievement of 250 µm thick.

Abstract

One of the processes that work in the field of engineering Proton Exchange Membrane Fuel Cell (PEMFC) is to produce a variety of designs MEA. The best design will be found in the manufacturing process. The project introduced a spray with a robotic instrument configuration x-y axis to issue MEA design. MEA layer forms which can be produced by this spray will follow a periodic function, whereas the layers including the thickness, porosity, pore diameter, specific active surface area which will be used to hold the chemical reaction to produce electricity. The character size coating layer is represented by the amount of spraying. This number is a function of the frequency of the robot, and the nozzle crosses the x-y dimensions of the substrate. Sprays produce two forms of MEA design. From the results of this study MEA quality can be assessed using a robot with a spray nozzle configuration as a contribution for Fuel Cell (PEMFC).
