An improved frying pan configured with two surfaceslevels, the first cooking surface used to cook foods and a second surface used to holdstore foods having a slope or pitch towards the outer perimeter of the frying pan. The aluminium foil coextrusion-coated in this way, to increase the adhesion strength between the aluminium foil and the plastic layer, then passes continuously through an oven with temperature set such that the temperature of the plastic layer and the adhesion-promotion agent lies above the crystallite melt point of the plastic. The method for making the catalyst can comprise: combining rhodium and a zirconium compound, wherein the zirconium compound has a morphology parameter of greater than or equal to about 800, to form a mixture, and disposing the mixture onto a substrate. At least a part of the hydrophilic fibers form aggregates that disperse in the sheet. The hydrogen source may be used to provide hydrogen fuel to a wide range of portable devices.
