摘要:
Electrode separator plate gas outlets are provided which have been modified in comparison to a standard electrode separator plate gas outlet to increase gas flow velocity and promote release of trapped water droplets in the flow field and gas outlet.

摘要:
An interlocking isolator for a proton exchange membrane fuel cell is provided which protects a fuel cell positioned in the interlocking isolator from electricity and heat. The interlocking isolator also permits multiple fuel cells positioned with the isolators to be stacked adjacently, thereby forming fuel cell stacks.
摘要:
A fuel delivery manifold enlarged in size is provided which, when incorporated into fuel cells which are then stacked allows for insertion of a baffle or a perforated fuel delivery tube through the fuel cell stack via the enlarged fuel delivery manifold to enhance and/or even out or equalize fuel delivery to all fuel cells in the fuel cell stack.
摘要:
A fuel cell stack (2) constructed and assembled so that a membrane-type humidifying exchanger (1) enables diffusional contact of a re-circulating aqueous liquid fuel supply and the oxidant air stream supplied to the fuel cell stack (2) is provided. The assembly is configured so that the fuel cell stack (2) is mounted together with other ancillaries on a base provided by the membrane-type humidifying exchanger (1).
摘要:
Apparatus (2) for degreasing of objects and with a mainly horizontal rotating drum (4) with an outer perforated tube (6) with at least one interior spiral (12) for guiding objects to be degreased, and with transportation means of the impeller type for liquid washing and rinsing agents, as the drum (4) is divided in at least two zones, respectively a washing (20) and a rinsing zone (22) and possibly a drying zone, the drum (4) consists of three concentric tubes in the form of said outer tube (6) of perforated plates or netting, an inner tube (8) and an inmost, central heating tube (10), through which hot air is lead to the inner tube (8) via radial nozzle openings (11), and between the outer (6) and inner tube (8) a spiral member (12) is placed, adapted to move the objects forward in the drum (4) passing the washing and rinsing zones (20, 22), while between the inner tube (8) and the inmost heating tube (10) an inverted twisted, inner spiral (18) is placed, adapted to move the objects back through the drum (4), as the objects after the rinsing zone are lead from the outer perforated tube (6) upwards and inwards into the inner tube (8).
