NOVELTY - The fuel cell comprises a flowable electrolyte suspension, a thixotropic electrolyte, and particles including a galvanic material. The particles are entrained in the electrolyte. The particles have a diameter of 30 microns, a mass of 0.5x 10-6 grams and a composite density of 2-6 times the mean density of their electrolyte-particle suspension, and are decorated with catalytic particles. The catalytic particles are attached to a skin of electrically-conducting material covering a metal core to form a charge transfer particle.    USE - The fuel cell is useful for converting chemical energy of hydrogen-containing fuels such as hydrogen, methane, methanol and borohydride into electrical energy.    ADVANTAGE - The efficient fuel cell has high current and power densities.    DETAILED DESCRIPTION - The fuel cell comprises a flowable electrolyte suspension, a thixotropic electrolyte, and particles including a galvanic material. The particles are entrained in the electrolyte. The particles have a diameter of 30 microns, a mass of 0.5x 10-6 grams and a composite density of 2-6 times the mean density of their electrolyte-particle suspension, and are decorated with catalytic particles. The catalytic particles are attached to a skin of electrically-conducting material covering a metal core to form a charge transfer particle. The skin of electrically-conducting material is decorated with nanoscale catalyst particles. The catalyst particles are nanoscale deposits of a metal. The catalytic particles have a core of a first metal that supports islands created by depositing a second metal in a process that displaces surface atoms of the first metal. The core is a metal having a density of 8 g/cm3. The fuel cell further comprises a unit for creating Taylor vortex flows in the electrolyte, a unit for creating circular couette flows in the electrolyte, first and second porous current collectors (106, 108) separated by a gap, a filter that is provided within the gap and divides the gap into an outer electrolyte chamber and an inner electrolyte chamber, and a unit for moving the filter within the gap to generate Taylor Vortex Flows in the electrolyte provided in the electrolyte chambers, a unit for pumping a fluid consisting fuel and oxidizer through one of the porous current collectors towards one of the electrolyte chambers, a unit for regulating temperature and pressure of the fluid to convert into a gas that creates an external electrolyte meniscus gas dome in the electrolyte outside of the electrolyte-facing surface of the porous current collector, and a unit for rotating the filter to create a vortex in the electrolyte in one of the electrolyte chambers. One of the current collectors is decorated with galvanic flakes, and includes a composite that contains a galvanic material coating. The electrolyte chambers are separated by the filter that is permeable to flow of the electrolyte in the electrolyte chambers.
