Abstract

An electrochemical cell includes a first electrode configured to operate as an anode to oxidize a fuel when connected to a load. The first electrode includes a permeable electrode body configured to allow flow of an ionically conductive medium therethrough. An electrode holder includes a cavity for holding the first electrode. A diffuser is positioned in the cavity between the first electrode and the electrode holder with a gap formed between the diffuser and the electrode holder. The diffuser includes openings configured to allow flow of the ionically conductive medium therethrough and to distribute the flow through the first electrode. A second electrode is positioned in the cavity on a side of the first electrode that is opposite the diffuser, and is configured to operate as a cathode when connected to the load and in contact with the ionically conductive medium.
