Additionally, the triazole-loaded PCMOF2 was incorporated into a H 2 / air membrane-electrode assembly and achieved an open circuit voltage of 1.18 V at 100 �C that was stable for 72 hours and managed to remain gas tight throughout testing.

The design emphasis for industrial users depends on the precise application and extends from the bottom end which is cost critical, to the most severe environments where the SCBA is one part of an integrated protective environment which includes gas tight suits for whole body protection and ease of decontamination.

Ceramics crumble, metal oxidises, plastics offgas and become brittle ( and are slowly eaten by fungii and degraded by sunlight ), gas-tight containers aren't that gas tight ( and the material of the box, and the seal, slowly contaminates the space within ).

(The problem has practical purpose as I want to get a flange through a hole into a sealed plastic gas collection bag, link this internal flange to an external flange fitted with a tube to give a gas tight seal-to get a tube for my gas collection bag to get it fit for purpose !)

The generator stator winding is water cooled at 2.155 m?/ min ( 474 gal / min ) and the stator core and rotor winding are cooled by hydrogen at 60 psig circulated by a blower on the shaft . To reduce the transport weight, each stator consists of an outer gas tight enclosure, which carries the hydrogen coolers and the end brackets which support the rotor bearings, and an inner stator comprising the magnetic core and windings.
