The present invention discloses a high-performance microbial fuel cell based on carbon with three-dimensional sieve tube structure as anode, comprising an anode and an electrode, wherein the anode is a carbon with three-dimensional sieve tube structure, and the three-dimensional sieve tube structure is a pie-shaped three-dimensional sieve tube structure or an annular-shaped three-dimensional sieve tube structure. The carbon with three-dimensional sieve tube structure is obtained by the carbonization of cassava straws which are agricultural solid residues. The high-performance microbial fuel cell based on carbon with three-dimensional sieve tube structure as anode according to the present invention has the features such as simple preparation method, easy to be amplified, environment-friendly, high power density and so on.

A fuel cell module according to the present embodiment includes a hydrodesulfurizer, a cell stack, an exhaust gas channel portion, and an air-preheating channel portion. The hydrodesulfurizer is configured to desulfurize fuel gas using a hydrodesulfurization catalyst. A reformer is configured to generate a hydrogen-containing gas. The cell stack is constituted by stacking a plurality of fuel cells and is configured to generate electric power. The exhaust gas channel portion is configured to discharge the hydrogen-containing gas, and discharge exhaust gas that is generated by the combustion of the oxygen-containing gas. The air-preheating channel portion is an air-preheating channel portion that is disposed so as to be adjacent to the exhaust gas channel portion and that is configured to preheat the oxygen-containing gas through heat exchange with the exhaust gas channel portion. The air-preheating channel portion is disposed between the hydrodesulfurizer and the cell stack.

A fuel cell system includes a plurality of fuel cell units each configured to generate lower-voltage DC power. The fuel cell system includes a plurality of DC-DC converters each electrically connected to each of the fuel cell units and configured to convert the lower-voltage DC power to higher-voltage DC power. The fuel cell system includes a primary load power conversion unit electrically connected to the plurality of DC-DC converters and configured to output a primary load. The fuel cell system includes an auxiliary load power conversion unit electrically connected to the plurality of DC-DC converters and configured to output an auxiliary load.

A collapsible fuel cell for an aircraft includes an inner textile support substrate having an outer surface including one or more textile crease lines forming a fold pattern and an outer shell layer conforming to the outer surface of the textile support substrate to form the fuel cell. The fuel cell is collapsible along the fold pattern formed by the one or more textile crease lines.

A fuel cell device is provided having an active central portion with an anode, a cathode, and an electrolyte therebetween. At least three elongate portions extend from the active central portion, each having a length substantially greater than a width transverse thereto such that the elongate portions each have a coefficient of thermal expansion having a dominant axis that is coextensive with its length. A fuel passage extends from a fuel inlet in a first elongate portion into the active central portion in association with the anode, and an oxidizer passage extends from an oxidizer inlet in a second elongate portion into the active central portion in association with the cathode. A gas passage extends between an opening in the third elongate portion and the active central portion. For example, the passage in the third elongate portion may be an exhaust passage for the spent fuel and/or oxidizer gasses.

Embodiments are directed to a method for fabricating a fuel cell. According to one embodiment, the fuel cell fabricating method includes the steps of laying up multiple strips of fabric over a mold to form an enclosure for the storage of fuel, and bonding the strips to one another using a bonding agent. When the bonding agent has cured, the mold may be removed from the enclosure.
