Aerosol-generating system including an aerosol-generating article, and an electrically operated aerosol-generating device

An aerosol-generating system, comprising:

• an aerosol-generating article including an aerosol-forming substrate, the aerosol-generating article having an outlet end and a distal end upstream from the outlet end;
• an aerosol-generating device that is electrically operated, the aerosol-generating device including a housing having a cavity, the cavity configured to receive the distal end of the aerosol-generating article;
• an electric heat-generating element;
• and
• a heat diffuser including a porous body for absorbing heat from the electric heat-generating element such that, in use, air drawn through the aerosol-generating article from the distal end to the outlet end is heated by the heat absorbed in the porous body, the porous body being made from a ceramic that is non-combustible, the porous body being configured to receive a distal end of the electric heat-generating element such that the distal end is embedded in the porous body.
