Gasket is one of the key components in proton exchange membrane fuel cells (PEMFCs), and the performance of the gasket can directly affect the durability and electrochemical performance of the PEMFCs. In this paper, the silicone rubber material, which is being considered as gasket material for PEMFC, was fabricated with different composite reinforcing fillers at different vulcanizing temperatures under different vulcanizing pressures. Effects of the composite reinforcing fillers (i.e., gas-phase SiO 2 and nano-CaCO 3 ), vulcanizing temperatures, and pressures on mechanical properties of the silicone rubber material were investigated. The tensile, hardness measurement, compression set, and compression stress relaxation experimental results show that the mass ratios of the gas-phase SiO 2 to nano-CaCO 3 , curing temperatures, and pressures had a significant impact on the mechanical properties of PEMFC gasket materials. It is found that the silicone rubber material cured at a vulcanization temperature of 160 C and a vulcanization pressure of 10 MPa had good compression mechanical properties compared to the materials cured at the other curing temperatures and curing pressures. Orthogonal test results show that, when mass ratio of the gas-phase SiO 2 to nano-CaCO 3 was 25:20, the silicone rubber material cured at the curing temperature of 160 C and under the curing pressure of 10 MPa had good compressive stress relaxation performance in this work.

This paper will demonstrate combination of optimum response for Tensile strength and Time curing which are obtained by combining elastomer, filler and co-accelerator at optimum level factors is the best way to overcome defect products. Data from this study will be obtained from 15 direct experiments based on RSM by using box-behnken design-Minitab 18 and response optimization was performed to get optimal response value combination from the expected target response. The analysis shows that all factors including elastomer, filler and co-accelerator have significant effect on tensile strength and time curing responses. The best composition to get the optimal combination of responses from certain response limits is elastomer = 70PHR, filler = 30PHR, and co-accelerator = 1.47PHR. The optimum value for tensile strength response is 15 kg/cm2 and time curing is 3.5 minutes. Beside as a solution for this problem, this optimization will increase production capacity of rubber strap 12.5% more that the factory decide to decrease production line and choose market development strategy to overcome access production and labor to new product base on polyurethane.

“…For example, Leblanc et al [8] investigated silicone rubber materials were affected by strain and strain rate (or frequency) at the room curing temperature, the test results were fully characterized not only with respect to their processing behavior but also in view of their chemical performances after cured. Javadi et al [9] studied the simulation of rubber curing process in a three-dimensional model. The final temperature of mold could significantly influence quality of final product.…”

The long-term mechanical stability of the gasket material is critical to sealing and electrochemical performance of the polymer electrolyte membrane (PEM) fuel cells. In this paper, the silicone rubber material, which is being considered as gasket material for PEM fuel cells, was fabricated at different curing temperatures and different curing pressures. Effects of the curing temperatures and curing pressures on the mechanical properties of the silicone rubber material were investigated. The tensile test results show that tensile strength of the specimen cured at the curing temperature of 160 was larger than that for the specimens cured at the curing temperature of 150 or 170 under the same curing pressure. The test results of the compression stress-strain, compression set and compression stress relaxation show that the curing temperature and curing pressure affected significantly the compression elastic modulus, compression set rate and compression stress relaxation behavior. It is found that the silicone rubber material cured at the curing temperature of 160 under the curing pressure of 10MPa had good compression mechanical properties compared to the materials cured at the other curing temperatures and curing pressure in this work.
