The ultimate goal of the project is to deliver:

• An Internal-Alcohol-Reforming High-Temperature PEM fuel cell

(IRAFC) with the following characteristics: (i) 0.15 W/cm2 at 0.7V, operating at 220°C (ii) Specific (W/kg) and volumetric (W/m3) power density similar to current, state-of-the-art high-temperature PEM fuel cells

• perating on hydrogen.

STRATEGY AND MILESTONES
