A waste reduction system that utilizes organic solids suspended in a waste stream to produce carboxylic acids, which can then be employed as an input to a microbial fuel cell or other biological processes to further enhance biogas production, is provided. The organic waste stream influent undergoes a multistage fermentation process in which fermentative microorganism metabolize the organic waste materials and produce one or more carboxylic acids, especially short chain fatty acids. The carboxylic acids serve as a food source for bacteria within an anode compartment of an MFC that generates useable electricity therefrom.

Accelerated testing protocols that can be utilized for determining and projecting the durability of SOFC cathodes are described. The accelerated testing protocols can be carried out under simulated operation conditions so as to provide in a matter of a few hundred hours data that can correlate to the condition of the cathode following operation of the cell over the course of a typical operation life span of several thousand hours. A testing protocol can include cycling a SOFC from OCV to operating potential at a predetermined current density. Each cycle can be relatively short, for instance less than one minute.

The present invention provides a fuel cell stack with enhanced freeze-thaw durability. In particular, the fuel cell stack includes a gas diffusion layer between a membrane-electrode assembly and a bipolar plate. The gas diffusion layer has a structure that reduces contact resistance in a fuel cell and is cut at a certain angle such that the machine direction (high stiffness direction) of GDL roll is not in parallel with the major flow field direction of the bipolar plate, resulting in an increased GDL stiffness in a width direction perpendicular to a major flow field direction of a bipolar plate.

The transmitter is arranged in a tire attached to a wheel and configured to transmit data to a receiver. The transmitter includes an obtaining section configured to obtain a detection result of the sensor, a generating section configured to generate the data including the detection result of the sensor, a transmitting section configured to transmit the data generated by the generating section, and an organic power generation element that is a power source of the transmitter. The organic power generation element is configured to generate power through a chemical reaction with organic matter contained in a fuel solution accommodated in the tire.

A light-driven fuel cell includes a cathode, an anode, and a proton-permeable membrane between the anode and the cathode. The anode includes a photocatalyst for anaerobic methane oxidation reaction, and when the anode is supplied with methane and water and is irradiated with light, methanol, protons and electrons are generated by anaerobic methane oxidation reaction from the methane and the water supplied to the anode; the protons pass through the proton-permeable membrane and move to the cathode; and the electrons move to the cathode via an external circuit. The cathode includes a photocatalyst for aerobic methane oxidation reaction, and when the cathode is supplied with methane and oxygen and is irradiated with light, methanol and water are generated by aerobic methane oxidation reaction from the methane and the oxygen supplied to the cathode and the protons and the electrons moved from the anode.

An adhesive tape includes a composite membrane and an adhesive layer, where the composite membrane includes a substrate and a hardening layer provided on a surface of the substrate, and a hardness of the hardening layer is 3H to 9H. The adhesive tape provided in this application has both small thickness and high hardness, which increases volumetric energy density of the electrochemical apparatus and can further effectively avoid tape wrinkling of the electrochemical apparatus.

Tubular ceramic structures, e.g., anode components of tubular fuel cells, are manufactured by applying ceramic-forming composition to the external surface of the heat shrinkable polymeric tubular mandrel component of a rotating mandrel-spindle assembly, removing the spindle from the assembly after a predetermined thickness of tubular ceramic structure has been built up on the mandrel and thereafter heat shrinking the mandrel to cause the mandrel to separate from the tubular ceramic structure.
