Abstract: MEAs are formed in regions corresponding to openings provided in a substrate. Each MEA includes an electrolyte membrane, an anode catalyst layer, and a cathode catalyst layer. The substrate has a first gas-impermeable region and a second gas-impermeable region between adjacent MEAs. A third gas-impermeable region is provided between the first gas-impermeable region and the second gas-impermeable region. The third gas-impermeable region having conductive property constitutes a part of interconnector.

Abstract: Embodiments relate to a performance enhancing layer for a fuel cell including one or more electrically conductive materials, at least one of the electrically conductive materials including particles which are morphologically anisotropic and oriented to impart anisotropic conductivity in the layer and a binder, wherein the binder positions the particles in contact with each other.

Abstract: A food production system having improved heat and nutrient recovery is disclosed. The system employs waste biomass and comprises a composter that partially composts the waste biomass, an invertebrate (e.g. worms) culture unit, a delivery subsystem to deliver partially composted waste biomass from the composter to the invertebrate culture unit in a temperature range suitable for the invertebrate culture, a food (e.g. fish or crustaceans) culture unit for producing the food operating in a temperature range suitable for the food culture, a delivery subsystem to deliver invertebrates from the invertebrate culture unit to the food culture unit, and a heat exchange subsystem providing for exchange of heat from the composter to the food culture unit. The subsystem comprises a controller for controlling the exchange of heat such that the food culture unit is maintained in the temperature range selected for the food culture.
