The production of H2 molecules during the era of large redshifts is calculated for standard and massive-neutrino cosmological models. The H2 formation kinetics corresponding to the processes: H + e - H(-) + hv, H(-) + H - H2 + e and H + H(+) - H2(+) + hv', H2(+) + H - H2 + H(+) are calculated and the results are described. It is found that the most effective process involves the reaction H2(+) + H - H2 + H(+). Asymptotically, H2 reaches a relative abundance 0.0001-0.0004.
