Preparation of Fuel Cell Stack Based on Fision Membrane

Preparation of single fuel cell stack using fision membrane of local materials has been done. In this research, beside preparation of fuel cell stack, the engineering side in the preparation of fuel cell stack also explored. The crucial steps of this research were on preparation of Membrane Electrode Assembly (MEA), stack construction, and flow field design used to distribute the fuel of hydrogen gas. The first two cases will be explained technically, but the third case, flow field design, will just be explained conceptually. In the preparation of MEA, in which fision membrane and Gas Diffusion Electrode (GDE) were assemblied, the compression factor must be noticed. Too high compression could caused crack in the GDE. However, low compression will result in a gap between membrane and GDE which could interfere the electron flow in the system and reduce the stack performance. At the stack construction, distribution of compression and leakage have also to be aware. These two factors could reduced the fuel cell stack performance drastically

Morphology Effect On Behaviour Of Phosphoricacidin Supramolecular Structured Polymer Membrane Fuel Cell

MORPHOLOGY EFFECT ON BEHAVIOUR OF PHOSPHORICACIDIN SUPRAMOLECULAR STRUCTURED POLYMER MEMBRANE FUEL CELL. Study on the effect of morphology on the conductivity of small molecules added polymer membrane for fuel cell has been done. The polymer electrolyte membrane fuel cell was made by constructing of supramolecular interaction between sulfonated polystyrene and polyethylene-graft-maleic anhydride. The small molecules used was benzimidazole and phosphoric acid. The addition of benzimidazole and phosphoric acid, was espected to improve to ionic conductivity. However, in this work it was observed that morphology of the membrane play vital roles in the final properties of the membrane. In other words, beside concentration of phosphoric acid the morphology affects the conductivity of polymer membrane fuel cell

Application of Sulfonated Polystyrene in Polymer Electrolyte Fuel Cell

APPLICATION OF SULFONATED POLYSTYRENE IN POLYMER ELECTROLYTE FUEL CELL. Sulfonated polystyrene (SPS) is polyelectrolyte solid that widely used in many aplications. In this works SPS is applied for some parts of polymer electrolyte fuel cell membrane due sulfonate group available in the structure. The investigation involve the application for membrane with addition of small molecules, i.e. benzimidazole and evaluating its microstructure and performance. Application of SPS solution as binding agent in MEA will also be presented. The results show that when using SPS as fuel cell membrane, the additon of small molecules such as benzimidazole would modify its microstrusture as well as improve its ion conductivity. Meanwhile, some improvement still required for application of SPS solution as binding agent for preparation of Membrane Electrode Assembly or MEA
