Fuel Cell Comprising at Least Two Stacked Printed Circuit Boards with a Plurality of Interconnected Fuel Cell Units

Abstract

A fuel cell comprising at least two stacked fuel cell boards (22) which each comprise a membrane of substantially gas impervious electrolyte material and at least two electrode pairs wherein the anode and cathode of each said electrode pair are arranged on respective faces of said membrane. An electrode of each pair of electrodes is connected to an electrode of an adjacent pair of electrodes by a through-membrane connection (13) or by an external connection on a Printed Circuit Board, comprising an electrically conductive region of said electrolyte material. A method for forming the through-membrane electrical connections in the electrolyte membrane is also disclosed.
