The content focuses on the requirements for producing a bipolar plate made from titanium. This is particularly interesting for the aviation industry, where weight is a big issue, as titanium is much lighter than stainless steel due to its low specific weight. On the other hand, the use of titanium brings different problems. For example, forming is not possible to the same extent compared with stainless steel, and welding is more complex due to an increased requirement for a protective gas atmosphere.
