摘要:
Provided are a dry-state detecting method and an electronic device system for a fuel cell, which detect the dry state of an electrolyte film precisely, and a power control method for optimizing the control of a starting time on the basis of the dry state detected. The fuel cell is constituted to include an electrolyte film, and a catalyst electrode and a gas diffusion electrode disposed on the two faces of the electrolyte film. The dry-state detecting method detects the dry state on the basis of a displacement of the electrolyte film in an in-plane direction.

In a viewpoint of the invention, a fuel cell system includes a fuel cell configured to generate a electric power by using fuel; a first assisting power source; a protecting circuit connected to the first assisting power source and configured to detect a failure in the first assisting power source; an auxiliary unit configured to supply the fuel to the fuel cell; a control circuit configured to control the fuel cell and the auxiliary unit; a first power converter configured to drive the control circuit by using electric power from the first assisting power source; and a first synthesizing section configured to synthesize a first electric power from the fuel cell and a second electric power from the first assisting power source to supply a synthesized power to a load.
摘要:
An ink jet recording head has a plurality of ink channels, disposed on a piezoelectric substrate, for receiving liquid ink therein, a plurality of dummy channels arranged alternately with the ink channels on the substrate, a top plate for covering the ink channels and dummy channels, and a nozzle plate defining the front end of the channels and having a nozzle for each of the ink channels for ink ejection. The dummy channels have a depth larger than the depth the ink channel, and the top plate has a slit extending along each of the dummy channels, for reducing cross-talks between adjacent ink channels.
