[1B04] Gas diffusion effect on H2 release caused by water radiolysis in geopolymers
Keywords:geopolymer, hydrogen, diffusion, safety
The present research shows experimental results of a strong decrease of the hydrogen production of water saturated geopolymers with their size (up to 200 times smaller than the literature value). Also, a predictive model based on gas diffusion and a pseudo first order reaction is described, in good agreement with the experimental results.
