(US5441822-A)      The electrode includes a porous catalyst layer having a thickness of about 0.1 mm and a porous diffusion layer having a thickness of about 1.6 mm. The catalyst layer includes a large number of agglomerate portions and a large number of gap portions which are alternately and almost parallelly arranged in a stripe-like manner. The agglomerate portion has a porous body having a porosity of 50 percent or more and consisting of fine carbon powder particles on which an alloy catalyst containing platinum as a main component is dispersed and carried, and an aqueous phosphoric acid solution serving as an electrolyte held in the pores of the porous body.    The gap portion is formed of a large number of water-repellent PTFE fibers having a porosity of 20 percent or more to connect the agglomerate portions.    ADVANTAGE -   Provides an electrode of a fuel cell having a higher output density than a conventional case with the same amount of catalyst.    (JP7235308-A)      The fuel battery electrode has a lower porous diffusion layer (12) and a porous catalyser layer (11). The porous catalyser layer has a thickness of 0.1mm and thickness of a porous diffusion layer is 1.6mm. The catalyser layer is formed in the shape of slots (14) and projections (13) formed alternately. The catalyser contains platinum alloy and carbon. The carbon particles to the extent of 13-50% is distributed in the porous catalyser layer. The pores in the electrode contain phosphoric acid as electrolyte. The above referred slots are filled up with PTFE fibers.    ADVANTAGE -   Increases power density.    (DE4447132-C2)      The catalyst layer (11) has numerous agglomerate parts (13) each with a conducting porous body stretching to the thick side of the electrode (10), an electrolyte-containing pore and numerous fissured parts (14) alternating with the agglomerate parts (13).    Each fissured part (14) has a bore hole through the catalyst layer (11) towards the thick side of the electrode and this hole has numerous liquid-repellent fibres, joining the neighbouring agglomerate parts (13) together.    USE/ADVANTAGE -   For use with fuel cell. Higher output density for same amount of catalyst.
