A fuel cell system includes a fuel cell, an oxidant gas passage, a cathode off-gas passage, a fuel gas passage, a circulation passage, an anode off-gas passage, a fuel shutoff valve, a supply device, a humidifier and a control device. The supply device supplies a scavenging gas, which is for scavenging the fuel cell, to the anode and the cathode. The humidifier humidifies the scavenging gas. The control device controls the supply device when the fuel cell is turned off so that supply of the fuel gas to the anode is shut off and the scavenging gas is supplied to the anode and the cathode, wherein supply of the scavenging gas to the cathode is conducted through the humidifier.

A fuel cell which can self-heat in a short time, in which no reaction gas is necessary for combustion, thereby improving the starting performance at low temperatures. The fuel cell comprises a cell structure in which an anode and a cathode are provided on either side of a solid polymer electrolyte membrane. This cell structure has a power generation plane and at least a part of the generation plane is defined as a local generation area so as to locally generate power. The fuel cell may include a pair of separators between which the cell structure is placed, and a reaction gas passage may be formed between the cell structure and each separator. One of a system for supplying a reaction gas to only a part of the reaction gas passage, and a system for supplying a reaction gas to the entire reaction gas passage is switchably selected.

Evaluation of an amount of immobilized sample in a surface plasmon resonance (SPR) immunoassay is provided. To immobilize the sample, a sensor unit has a sensing surface. The sensor unit includes a transparent dielectric medium, and a metal film having the sensing surface. The metal film is connected with the dielectric medium for constituting a metal/dielectric interface. The sensing surface is adapted to sensing reaction of the sample. Then illuminating light reflected by the metal/dielectric interface is received with a photo detector such as a CCD upon applying the illuminating light to the metal/dielectric interface, to detect attenuation of the illuminating light and output a detection signal thereof. The evaluated amount of the sample immobilized on the sensing surface is evaluated according to the detection signal. Before immobilization, the sensor unit is tested for the photo detector to output an initial detection signal, which is considered for the evaluation.
摘要:
A system and method for draining remaining water in a gas passage of a fuel cell, which has a simple structure and the remaining can be efficiently and reliably drained outside. Water which remains in a gas passage of the fuel cell is first drained by increasing the flow rate of the reaction gas while the operation of the fuel cell is stopped. The remaining water which has not been drained is then drained by increasing the pressure of the reaction gas and then decreasing the increased pressure. The increase and decrease operation of the pressure of the reaction gas is started after the increase of the flow rate of the reaction gas is started. Typically, the increase of the pressure of the reaction gas is started when a predetermined time has elapsed after the increase of the flow rate of the reaction gas is started.
