The present study explores the characteristics of hydrogen energy literature from 1965 to 2005 based on the database of Science
Citation Index Expanded (SCIE) and its implication using the bibliometric techniques. The results of this work reveal that
the literature on hydrogen energy grows exponentially with an annual growth rate of about 18% for the last decade. Most of
document type is in the form of journal articles or meeting abstracts, constituting 90.17% of the total literature and English
is the predominant language (94.66%). USA, Japan and China are the three biggest contributing countries on hydrogen energy
literature publishing, 25.8%, 14.9%, 7.7%, respectively. The Chinese Academy of Sciences in China is the largest contributor
publishing 308 papers. The journal literature on hydrogen energy does not confirm the typical S-shape for the Bradford-Zipf
plot, but five core journals, i.e. International Journal of Hydrogen Energy, Journal of Power Source, Journal of the Electrochemical Society, Solid State Ionics,
and Electrochimica Act, contributing about 41% can be identified. Journals with highly cited articles and most highly cited articles are also identified,
in which the most highly cited article receives more than 1,000 citations.

This study explores boundary-crossing networks in fuel-cell science and technology. We use the case of Norwegian fuel cell
and related hydrogen research to explore techno-science networks. Standard bibliometric and patent indicators are presented.
Then we explore different types of network maps — maps based on co-authorship, co-patenting and co-activity data. Different
network configurations occur for each type of map. Actors reach different levels of prominence in the different maps, but
most of them are active both in science and technology. This illustrates that to appreciate fully the range of science-technology
interplay, all three analyses need to be taken into account.
