Technical porous nickel

Previously, it was not possible to produce deep drawn parts with different grain structures. Through the new TPN (technical porous nickel) forms technology, it becomes...

The use of a particular catalyst for HOR in alkaline media depends on the operating conditions and cost. For example, non-noble metals such as nickel [37] have been used in H2 technical electrodes for AFCs. It is known that the catalytic activity of Raney Ni (porous Ni doped with Co or alloyed with Fe, Ti or Mo to improve its performance) approaches that of noble metals in these systems. Another catalyst that has been used is nickel boride (Ni2B). Sodium tungsten bronzes [38] and carbon supported Pt and Pt-Pd [39] have also been employed to eatalyze HOR in alkaline solutions. 

A vacuum soldering process is the second technical process of relevance. It is used to solder the porous metallic substrate on the intereonnect whereby a nickel-based solder foil is applied [73].
