摘要 |
<p>The invention is a fuel cell(8) made of a fuel plenum(10) with fuel(11), an oxidant plenum(16) with oxidant(13), a porous substrate(12) communicating the fuel(11) and oxidant plenum(16), a channel(14) formed by the porous substrate, an anode(28), a cathode(30), electrolyte(32) in a portion of the channel contacting the anode and the cathode preventing transfer of fuel to the cathode and preventing transfer of oxidant to the anode, a first coating(34) to prevent fuel from entering a portion of the porous substrate, a second coating(36) to prevent oxidant from entering a portion of the porous substrate, two sealant barriers(44,46), and a positive(50) and negative(48) electrical connection, wherein the invention also involves a multiple fuel cell layer structure, a bi-level fuel cell layer structure, and a method for making a fuel cell layer.</p> |
