Activity of Patents in Fuel Cells and Hydrogen Production in the Context of Passenger Car Fleet in the V4 Countries

The hydrogen market in the world today is capable ovule and empirical evidence on activity of patents in fuel cells and hydrogen production is limited so far. Patent applications in zero-emission mobility in the aspect of fuel cells include: DAFC/DMFC&DMFC, PEMFC, SOFC, AFC, PAFC. As for the patents relating to the hydrogen production, they concern low carbon, electrolysis and inorganic. The purpose of the study was to investigate certain aspects of the activity of patents in fuel cells and hydrogen production in the context of passenger car fleet in the Visegrad group (V4) countries and to explore the relationship between patent registrations and GDP per capita in V4. The research area relates to the answer to the question of whether a country’s involvement in zero-emission patent activity (patents in fuel cells and hydrogen production) could contribute to the renewal of the country’s passenger car fleet. The theses were formulated as follows: 1) activity of patents in fuel cells and hydrogen production in the V4 countries doesn’t depend on the car fleet in these countries, 2) the level of GDP per capita in the V4 countries is not followed by the number of patents registrations in hydrogen technology, 3) the highest patent activity in fuel cells and hydrogen production doesn’t mean that the car fleet in these country will be zero-emission in coming years. The method used in this article is a comparative analysis, but also the relationships between patent registrations, GDP per capita and passenger car fleet in V4 are considered
