Summary
Recognizing the critical role played by science and technology in the development of fuel cells, this article aims to characterize the evolution of the S&T knowledge bases of fuel cells over the nineties, using data on patents and scientific publications. The field of fuel cells is particularly heterogeneous. It covers diverse sub-fields that are marked by idiosyncratic characteristics (e.g. actors, demand, and input) and different historical developments. Although this heterogeneity of the field of fuel cells is reflected in the dynamics of S&T knowledge generation within and across its sub-fields too, this article shows that it does not entail the absence of cognitive interrelations between their S&T knowledge bases. For that purpose, the article uses “simultaneous mapping' approach of their S&T knowledge bases by means of textual analysis.
