The effects of wall outgassing on the H-mode pedestal recovery after edge localized mode (ELM) crash is examined with a simplified model of hydrogen adsorption/desorption processes. The parameters governing the dynamics of the wall response to the ELM crash are found. It is shown that within adopted hydrogen adsorption/desorption model a significant impact of the wall outgassing on the pedestal recovery can be observed for the wall surface temperature range between 500 K and 800 K.
