GM and Dow launched a joint project in 2004 for proving the viability of hydrogen fuel cells. In the first phase, a single GM test cell was connected to Dow s power distribution grid and also to Dow s hydrogen clean-up and pipeline system to generate electricity for the Dow chemical plant. Phase II expands the project from a single GM test cell to a multi-cell pilot plant at Dow s Texas Operations in Freeport, Texas. 

In Chapter 10, the use of membranes for different applications are described. One of the possible membranes for hydrogen cleaning is an asymmetric membrane comprised of the dense end of a proton conduction perovskite such as BaCe0 95 Yb0 05O3 5 and a porous end to bring mechanical stability to the membrane. In this case, it is possible to take from the slurry, obtained by the acetate procedure, several drops to be released over a porous ceramic membrane, located in the spinning bar of a spin-coating machine. Thereafter, the assembly powder, thin film porous membrane is heated from room temperature up to 1573 K at a rate of 2K/min, kept at this temperature for 12 h, and then cooled at the same rate in order to get the perovskite end film over the porous membrane [50],...

The trivalent phosphorus compound activates ammonia-borane to furnish a dihydri-dophosphorane (22), which in turn is shown to transfer hydrogen cleanly to azobenzene, yielding diphenylhydrazine and regenerating the initial trivalent phosphorus species." ...
