Abstract
Global warming has correlation with CO2 emissions. The emission coupled with rising energy prices led to concerns
of people. Those problems are critical issues to encourage steps for reducing the risk to humans and the
environment. One of the important efforts to achieve clean technology is to replace fossil-based energy with
renewable-based energy system and to develop non-carbon based energy. One type of non-carbon based energy is
hydrogen fuel cell (Proton Exchange Membrane Fuel Cell, PEMFC). The studies of the development of hydrogen
fuel cell (FC) at this time lead to the provision of hydrogen, the discovery of non-platinum catalyst, and the finding
of fabrication methods of PEMFC. The acquiring of raw material for non-platinum catalyst and hydrogen using
local raw material is an important effort to reduce the cost of fuel cell system. Non-platinum catalyst is much
cheaper than platinum and more resistant to CO poisoning. The catalyst candidate is selected from the class of
transition metals as active components of supported by the substituted N-Carbon Nano Tube (CNT). In FC system,
electrodes are made by coating method in which carbon paper as a substrate with a liquid (sol) which contains
catalyst precursors, transition metal catalyst, N (Dimethyl Formamide), and C of resorcinol- formaldehyde. Using
this method, catalyst-candidate in liquid phase coated onto the carbon paper which as a substrate. Then the
substrate need drying for sol changed into a gel. To activate the catalyst, substrate with the candidate of the catalyst
must be pyrolysed in order to obtain an expected catalyst (transition metal / CNT / N). When the catalyst attach to
the substrate (carbon paper), the catalyst could be a distributor of hydrogen and oxygen moving to the catalyst
surface. The direct coating method would produce the electrode with a certain thickness of catalyst. The certain
thickness can be controlled by adjusting the composition of the components in the sol and during pyrolysis and
reduction processes. Therefore the electrode with non-platinum catalysts that has similar performance and stability
with platinum catalyst could be achieved. Thus the results of this study might be an idea to solve the problem of the
mass production of PEMFC with lower production cost.
