摘要： A fuel cell control system is provided which is designed to ensure the stability of operation of a fuel cell stack. The system includes a magnetic sensor and a controller. The magnetic sensor works to measure a change in magnetic flux density of magnetic field produced by an electric current as generated by electrochemical reaction taken place in each of fuel cells. The controller is designed to analyze the change in magnetic flux density measured by the magnetic sensor to specify the cause and location resulting in a drop in ability of the fuel cell stack to generate electricity which is to occur partially in the fuel cell stack. The controller takes a predetermined measure to control the operation of the fuel cell stack for eliminating the drop in ability of the fuel cell stack to generate the electricity.

Each sealing gasket-combined membrane electrode assembly includes a membrane electrode assembly and a sealing gasket portion. One of the sealing gasket portion and the separator has a protrusion formed on each face and extending in a stacked direction in which the separators and the sealing gasket-combined membrane electrode assemblies are stacked. The other of the sealing gasket portion and the separator has a recess in which the protrusion is fitted. The protrusions formed respectively on opposed faces of the successive sealing gasket-combined membrane electrode assemblies or the successive separators are located at different positions.

摘要： A fuel cell including separators opposing each other and squeezing a power generating reaction portion. Each of the separators includes a gas passage, a gas passage dividing rib, and a protrusion formed in the gas passage. In a first separator, which is an at least one separator of the separators opposing each other via the power generating reaction portion, at a region of the first separator opposing a gas passage dividing rib of a second separator, which is a separator opposing the first separator, a squeezing rib is formed and replaces the protrusion. The squeezing rib and the gas passage dividing rib of the second separator squeezes the power generating reaction portion. At the region of the first separator, a contact area of the squeezing rib with the power generating reaction portion is adapted to be larger than a contact area of the protrusion of the first separator with the power generating reaction portion in a case where the protrusion were formed without forming the squeezing rib.

It comprises a battery-cell group wherein a plurality of battery cells and separators are arranged; and terminal plates 1 and end plates 3 that are arranged on each end portion of the battery-cell group. The end plates 3 are formed as metal plate members having surfaces 31 opposing to the terminal plates 1. A polyimide film 35 is formed as an insulating resin layer at least on the opposing surface 31 of the end plate 3 for electrically insulating between the end plate 3 and terminal plate 1 by an electro-deposition coating method.
