Abstract: An electrical connector including an insulator body, a shield, and an upper and lower rows of terminals held in the insulator body. One of the two rows of terminals is a row of low speed circuit terminals, and the other one is a row of high speed circuit terminals. The row of high speed circuit terminals includes two pairs of high speed differential signal terminals, and each of the high speed differential signal terminals has a contact portion, an insertion portion and a connection portion between the contact portion and the insertion portion. A part of the connection portion of the high speed differential signal terminal is folded away from the low speed circuit terminal to form a folding section. It increases the space between the high speed differential signal terminal and the low speed circuit terminal and effectively reduces the capacitive coupling crosstalk therebetween.

Abstract: The present invention discloses an electrical connector having an insulator body, a shield, and an upper and a lower rows of terminals. The shield is constructed to enclose the insulator body. The upper and a lower rows of terminals are held in the insulator body, wherein one of the two rows of terminals is a row of low speed circuit terminals and the other is a row of high speed circuit terminals having two pairs of high speed differential signal terminals and a first ground terminal. At least a portion of the first ground terminal has a width larger than a corresponding portion of each of high speed differential signal terminals. The ground terminal of the high speed circuit is widened compared with high speed differential signal terminals, and it can effectively reduce the inductive coupling crosstalk between the high speed differential signal terminals.

Abstract: A membrane electrode assembly of a fuel cell comprises a proton exchange membrane, two metal-carbon (carbon supported metal) catalyst layers, two gas diffusion layers and at least two metal catalyst layers. The proton exchange membrane is at the center of the membrane electrode assembly, the two metal-carbon catalyst layers are located on both sides of the proton exchange membrane. The two gas diffusion layers are on both outer surfaces of the membrane electrode assembly. The metal catalyst layers are located at the interface between the proton exchanged membrane and the metal-carbon catalyst layer and/or at the interface between the metal-carbon catalyst layer and the gas diffusion layer. The combinations of metal-carbon catalyst and metal-catalyst layers reduce the thickness of catalyst layer and maintain a high catalysis activity, and thus improve the fuel cells performance.
