ZeroAvia today announced that it has been awarded nine new patents this year so far, with many critical to the company’s roadmap for scaling hydrogen-electric engines for large regional aircraft. The company has now been granted a total of 45 patents related to hydrogen and electric aviation systems, with almost 250 applications, most of which are still going through the patent office pipelines.  

Also important for scaling hydrogen-electric engines for large aircraft is the delivery of fuel cell systems with higher specific power. UK patent office GB2614450 covers novel coatings for aluminium bipolar plates for high temperature PEM (HTPEM) fuel cell systems, allowing the higher temperature operation with lightweight metals, while overcoming material degradation challenges.
