Metal membrane contains a metal membrane formed on a supporting surface of a porous membrane carrier. The pores of the membrane carrier are closed in the region of the supporting surface using an auxiliary material before applying the metal membrane and op...

Production of a metal composite membrane consisting of a thin metal membrane having a required thickness and a metallic membrane support having a porous structure comprises placing a precursor of the metal membrane on a porous precursor of the membrane sup...

The present invention provides nanoparticles which contain noble metals alone or noble metals in combination with base metals. The nanoparticles are characterised in that they are embedded in an aqueous solution of a temporary stabiliser based on a polysac...

Ink contains a catalyst material, an ionomer, water and an organic solvent consisting of a compound of linear dialcohols having a flash point above 100 degrees C in a concentration of 1-50 wt.%.

Membrane-electrode unit consists of a polymer electrolyte membrane having a first side and a second side both having porous reaction layers and gas distributor layers. The reaction layers contains precious metal catalysts supported on carbon, and ionomers....

The electrical recovery of energy, comprising using a fuel cell by reforming an organic fuel, removing carbon monoxide from the reformate and converting the hydrogen in the reformate and the oxygen into electrical energy, where the reformate is treated in ...

A second lambda sensor is not employed for monitoring until, under conditions of rich exhaust, its output voltage lies no more than a given potential difference above a desired value.

Nitrogen oxide (NOx) and soot removal from lean combustion engine exhaust gas with low sulfur oxide (SOx) concentration involves passing the exhaust gas through a storage catalyst adsorbing NOx and SOx under lean exhaust gas conditions and a particle filte...
