新水素エネルギー（”常温核融合”）研究の最近の動向

抄録

Current status of so called cold fusion (new hydrogen energy) research is reviewd. Researches in last 7 years after March 1989 have established the following facts: a) There happen surely anomalous excess heats sometimes in heavy water electrolyses with Pd cathodes. b) During the excess heat generation, no correspondingly intense d-d fusion takes place. c) Excess heat correlates with D/Pd>0.85, electrolysis current density > 0.2 A/cm² and dynamic loading condition. d) No correlations in-situ with primarily emitted radiations (charged particles) are observed. e) A few un-identified reports on He-4 production as nuclear ash which have never been claimed should be many times duplicated by future efforts. The key for the future of new hydrogen energy is resolving "nuclear or chemical issue" for excess heat.
