Molten carbonate fuel cell

摘要

A molten carbonate fuel cell, which makes a separator unnecessary, cuts down the number of components, and markedly reduces the costs, is provided. In the cell, a cathode, an electrolyte plate holding an electrolyte, and an anode are provided concentrically with a tube body, the electrolyte plate is held by the anode, and the electrolyte plate is sandwiched between the anode and the cathode, so that the cell is constructed without the use of a separator.

主权项

1. A molten carbonate fuel cell, comprising:
a tube body having many holes in a tubular surface thereof; a tubular first electrode provided around the tubular surface of the tube body; a tubular electrolyte plate which is provided around the first electrode, which the first electrode contacts, and which holds an electrolyte; and a tubular second electrode which is provided around the electrolyte plate, and which makes contact with the electrolyte plate to hold the electrolyte plate, wherein an oxidant gas or a fuel gas is supplied inside the tube body, and a fuel gas or an oxidant gas is supplied to the second electrode, whereby an electrochemical reaction occurs to obtain electric power, the first electrode is a cathode, and the second electrode is an anode, a material constituting the anode is sintered, whereby the anode is clamped diametrically inwardly, and the electrolyte plate is sandwiched and held between the anode and the cathode, and the oxidant gas is supplied from inside the tube body to the cathode through the many holes, and the fuel gas is supplied to the anode.
