Abstract
The fuel cell base module stacking structure has large compactness, very litte ohmic losses and ease as for implementing the seal of the assembly. It consists of a concentric stack of several fuel cell base cells each consisting on either side of an interconnector (24) sandwiching an anode (21), an electrolyte (22) and a cathode (23), each cell being thereby placed upon each other. The module is completed with two cases for distributing combustible gases. Application to gas fuel cells of the SOFC type.
Claims21
A fuel cell module consisting of a stack of a plurality of cells with each cell composed of multi-layers corresponding to an anode, a cathode and an electrolyte with each of the layers of each cell superimposed upon one another such that all of the cells in the stack lie coaxial and concentric to one another within a tubular architecture and with the concentric cells connected through interconnectors,
- characterized in that the superimposed cells in the stack are separated by interconnectors located between the superimposed cells with the fuel cell module forming a structure having a distribution case disposed on opposite ends of the structure facing the layers of each cell, with the distribution case having gas supply means comprising radial channels opening from at least one surface of the distribution case adjacent each opposite end of the structure.
