    Abstract: The present invention discloses an electrochemical generator fed with reactant gases, and in particular a fuel cell fed with a hydrogen-containing gas and with air at near ambient pressure. The electrochemical generator is characterised by asymmetry of the pressure drops localised in the distributing and collecting channels, wherein, in particular, the pressure drop concentrated in the collecting channels is substantially higher than that concentrated in the distributing channels. Moreover, the pressure in the active areas of the generator substantially coincides with the feeding one. Such a result is obtained by differentiating the design of the distributing channels from the one of the collecting channels, whose passage section is lowered and/or whose length is increased and/or whose amount is decreased.

    Abstract: The present invention describes a membrane fuel cell capable of operating in a stable fashion at high currently density under dry reactant gas feed at near-atmospheric pressure. This result is obtained by employing internal porous gas distributors, such as three-dimensional reticulated materials, sintered materials, juxtaposed meshes or expanded sheets, and at the same time by countercurrent-feeding the gas reactants, preferably ambient air, from the bottom. In one preferred alternative liquid water is injected from the bottom into the air feed: with these operating conditions, an extremely simplified stable functioning is obtained, since the air and water flow-rates, adjusted as requested for the maximum nominal electrical output, are kept unvaried even at low or zero output conditions without the cell membrane undergoing dehydration.

    Abstract: A description is made of a flexible spacer for double glazing made of Polyisobutylene elastomer or butyl rubber IIR (simple or halogenated), suitably loaded with both reinforcing and inert fillers. The spacer can be cross-linked with sulphur or peroxides. The spacer is impermeable to moisture and has high low thermal conductivity gas sealing capacity, and incorporates moisture absorbing material. In particular, the spacer features - on each side wall - at least a small wave (13a) positioned immediately above the accumulation area of the internal or primary sealant (15) so as to ensure an optimal adhesion to the glass of the double/triple glazing unit within which the spacer is fitted and features at least one recess (13b), with a configuration such as to allow the external sealant to penetrate and create a strong mechanical bond between the two materials.
