Fuel Cell

A fuel cell includes a membrane electrode assembly and a first separator. The first separator includes a first reactant gas channel, a first reactant gas manifold, and a first buffer portion. The first buffer portion is located outside of a power generation region of an electrode catalyst layer of the first electrode. The first buffer portion connects the first reactant gas channel to the first reactant gas manifold. A gas diffusion layer of the first electrode extends along a surface of the first separator to a first buffer region facing the first buffer portion. An intermediate layer of the first…

Fuel Cell Stack

A fuel cell stack includes a bracket and a boss. The bracket includes an attachment surface. The bracket includes an attachment and detachment hole and an opening hole. The boss includes a bearing surface and a locking surface part. The locking surface part is connected to the bearing surface and protrudes in an outside direction such that at least a part of the locking surface part overlaps with the attachment surface part viewed from an attachment direction when a center of the attachment and detachment hole coincides with a center of the bearing surface.

Microbial Electrochemical Cells and Methods for Producing Electricity and Bioproducts Therein

Bioelectrochemical systems comprising a microbial fuel cell (MFC) or a microbial electrolysis cell (MEC) are provided. Either type of system is capable of fermenting insoluble or soluble biomass, with the MFC capable of using a consolidated bioprocessing (CBP) organism to also hydrolyze an insoluble biomass, and an electricigen to produce electricity. In contrast, the MEC relies on electricity input into the system, a fermentative organism and an electricigen to produce fermentative products such as ethanol and 1,3-propanediol from a polyol biomass (e.g., containing glycerol). Related methods are also provided.

Membrane Electrode Assembly for Polymer Electrolyte Fuel Cell, Method of Producing the Same and Polymer Electrolyte Fuel Cell

An object of the present invention is to provide a membrane-electrode-frame assembly which suppresses reductions in power generation properties due to gas cross leakage of a polymer electrolyte fuel cell, which improves durability of a polymer electrolyte membrane and which exhibits superior productivity. In the membrane-electrode-frame assembly, an unwoven fabric which has two domains each having different pore sizes and which is formed with fibers of PVDF is disposed as a reinforcing membrane in a polymer electrolyte membrane for a polymer electrolyte fuel cell, and a domain having a smaller pore size and protruding from the polymer electrolyte membrane and…

Fuel Cell System and Fuel Cell System Control Method

To provide technology that is capable of inhibiting a decrease in starting properties of a pump in a low-temperature environment. A fuel cell system is equipped with a control unit, a fuel cell, and a pump. The control unit acquires the temperature of the fuel cell as a parameter expressing the temperature of the pump while operation of the fuel cell is stopped. The control unit rotates rotation body of the pump when it is detected that the temperature of the pump is a threshold value or less set within a predetermined range lower than the freezing point based on…
