Membrane Electrode Joint Product and Solid Polymer Electrolyte Fuel Battery

The objective of the present invention is to provide a membrane electrode assembly, and a solid polymer electrolyte fuel cell having the assembly. The assembly has a member that has excellent gas sealing properties, and at the same time, is capable of improving electrode membrane strength. In the assembly, the polymer electrode membrane is not deteriorated. Further, the assembly is easy to be built up, since the number of components is small. The membrane electrode assembly for a solid polymer electrolyte fuel cell of the present invention is characterized in comprising a polymer electrolyte membrane, a fuel electrode layer and an air electrode layer located respectively on each surface of the membrane, and a fuel electrode diffusing layer and an air electrode diffusing layer located respectively on the fuel electrode layer and the air electrode layer; wherein an area of a planer section of the polymer electrolyte membrane is slightly larger than areas of planer sections of the fuel electrode layer and the air electrode layer; a reinforcing frame formed of a thermosetting resin is located on a part of the polymer electrolyte membrane where the fuel electrode layer or the air electrode layer is not formed on one side or both sides thereof; and a protective later exists in at least a part between the polymer electrolyte membrane and the reinforcing frame.

Nerve blocking indwelling catheter needle with resistance measurement device

A nerve blocking indwelling catheter needle with a resistance measurement device comprises a needle core (6), a catheter (1), and a pressure detection device. The needle core (6) penetrates through the catheter (1), and a tail end of the catheter (1) is connected to a connection tube (19). A rubber plunger (4) is disposed in the connection tube (19). The needle core (6) penetrates through the rubber plunger (4), and a side tube (3) is disposed on a side wall of the connection tube (19) in front of the rubber plunger (4). A channel is disposed in the needle core (6). An opening (5) is disposed on a side wall of the needle core (6) that is located in the connection tube (19) and in front of the rubber plunger (4), and the opening (5) is in communication with the channel. The pressure detection device comprises a shell (20). An inner rod (11) is disposed in the shell (20), and a front end of the inner rod (11) is connected to a rear end of the needle core (6). A pressure sensor (12) is disposed between a tail end surface (13) of the shell (20) and a tail end surface of the inner rod (11), and the pressure sensor (12) is connected to a measurement circuit through a signal wire (17). The measurement circuit is connected to a display device (18). When a needle tip (61) breaks through tunica vaginalis, the pressure on the needle tip (61) has a great difference, and the difference is expressed through the display device (18), so as to prompt operating personnel that the nerve block enters the tunica vaginalis and is adjacent to the nerve to be blocked. The catheter needle is simple and convenient in operation and does a small damage to the nerve.
