What confused me in the OP (and still does) was not the terms "graded" and "connected". It was the expression "positive dimensional part of $H$" and the distinction between the "kernels" $H$ and $I$ - as i said in my comments above. | |

The homology of an H-space (and H is for Hopf!) with field coefficients is a graded cocommutative Hopf algebra. | |
