Claim Text:
1. An electrochemical storage cell comprising: a housing; a solid electrolyte tube, which defines an inner space of the housing as a first electrode chamber and a second electrode chamber; a first electrode material in the first electrode chamber; a second electrode material in the second electrode chamber; an electron channel unit formed of a porous carbon-based felt and arranged in the second electrode chamber for guiding movement of electrons in the second electrode chamber, the electron channel unit comprising a center portion and a first edge and a second edge at opposite sides of the center portion, the porous carbon-base felt having a thickness that decreases from the center portion of the electron channel unit toward the first edge of the electron channel unit; and a metal current collector adjacent to the porous carbon-based felt and exposed to an outside of the housing, wherein a shortest distance between the solid electrolyte tube and a portion of the porous carbon-based felt that is between the center portion and the first edge is less than a shortest distance between the solid electrolyte tube and the first edge.
