“…Before the cell test, a leak test using nitrogen gas was performed to ensure that the single cell was gastight. Then, a constant current (CC) mode was applied to activate the MEA [34,35,39]. The electronic load was controlled by the software, NOVA version 1.3, and interfaced with a computer for data collection.…”

“…The matrix that will results is a rigid network with pores of under one micrometer and polymer chains with a medium length of over a micrometer [11]. The direct immobilization of the active substance (enzymes, antibodies, proteins, DNA, and ARN) will lead to the physical entrapment that can take place due to the specific properties of siloxane matrices: adjustable porosity, chemical persistency, mechanical and optical stability, normal expandability, thermic stability [12]. Encapsulating the biomolecules without altering their initial conformation represents the main advantage of the controlled release systems; this property exists due to the recesses that ensure a rigid environment for the encapsulated molecule [13,14].…”

“…The most common low Pt or Pt alloys are supported by high specific surface area carbon and are used in both the anode and the cathode. To achieve high catalytic performance with low Pt loading, considerable effort must be placed on Pt utilization and improvement of its electrochemical activity [3,[5][6][7]. The electrochemical activity depends not only on the unique nature of the Pt or Pt alloy catalysts, such as their size, size distribution, shape, and oxidation state, but also on the morphological structures of the carbon support and metallic nanoparticles, such as the carbon specific surface area, carbon aggregation, metal dispersion, and metal-carbon interactions [8][9][10].…”
