Claim Text:
1. An electrochemical cell comprising: a fuel electrode comprising a metal fuel and a current collector; an oxidant electrode spaced from the fuel electrode; an ionically conductive medium for conducting ions between the fuel and oxidant electrodes to support electrochemical reactions at the fuel and oxidant electrodes; a catch tray consisting essentially of a catch tray body that is mounted and positioned within a flow path of the ionically conductive medium to be contacted by particulates of the metal fuel separating from the fuel electrode, the catch tray being disconnected from the current collector of the fuel electrode; and an electrode holder supporting the fuel electrode, the electrode holder comprising one or more recesses therein for receiving and securing a mounting portion of the catch tray; wherein the fuel electrode and the oxidant electrode are configured to, during discharge, oxidize the metal fuel at the fuel electrode and reduce an oxidant at the oxidant electrode to generate a discharge potential difference therebetween for application to a load; and wherein the catch tray body has a catalyst material for catalyzing, locally at the catch tray, oxidation of particulates of the metal fuel disconnected from the current collector of the fuel electrode and contacting the catch tray body, and reduction of cations in the ionically conductive medium.
