There is disclosed a refrigerating apparatus which can more efficiently cool the inside of a chamber to an ultralow temperature. In a refrigerating apparatus R1 which condenses a refrigerant discharged from a compressor 14, reduces a pressure of the refrigerant by a capillary tube 18 and evaporates the refrigerant by an evaporator 13 to exert a cooling function, the capillary tube 18 is passed through a suction piping line 32 through which the refrigerant returning from the evaporator 13 to the compressor 14 flows, to constitute a double tube structure. Furthermore, the suction piping line 32 (a piping line 32A) formed in the double tube structure by passing the capillary tube 18 therethrough is surrounded with an insulating material 35.

A refrigerating apparatus includes a refrigerating cycle including a compressor, a condenser, a flow divider, a first heat exchanger, a second heat exchanger, a decompressing device, and an evaporator. The refrigerant cycle has sealed therein a mixed refrigerant obtained by mixing at least first to third refrigerants with different evaporation temperatures. The first heat exchanger and the second heat exchanger each includes a double pipe to form a first flow passage in an inner pipe of the double pipe, a second flow passage in an outer pipe of the double pipe, and an intermediate port in a piping connecting between the second flow passage of the first heat exchanger and the second flow passage of the second heat exchanger. A high-temperature and high-pressure refrigerant discharged from the compressor is cooled by the condenser to liquefy the first refrigerant having a high evaporation temperature into a liquid refrigerant.

The durability of a polymer electrolyte fuel cell is very significantly improved by using a tightening pressure of about 2 to 4 kgf/cm2 of area of electrode; or a tightening pressure of about 4 to 8 kgf/cm2 of contact area between electrode and separator plate; or by selecting a value not exceeding about 1.5 mS/cm2 for the short-circuit conductivity attributed to the DC resistance component in each unit cell; or by selecting a value not exceeding about 3 mA/cm2 for the hydrogen leak current per area of electrode of each MEA. Further, in a method of manufacturing or an inspection method for a polymer electrolyte fuel cell stack, fuel cells having high durability can be efficiently manufactured by removing such MEAs or unit cells using such MEAs or such cell stacks having short-circuit conductivity values and/or hydrogen leak current values exceeding predetermined values, respectively.
