  "textContent": "A fuel cell module (FC) comprises at least two substantially rectangular FCs, each of which includes an anode with a current collector and an insulating frame positioned along the periphery of the anode and forming an anode chamber, a cathode with a current collector and an insulating frame positioned along the periphery of the cathode and forming a cathode chamber, and an electrolyte chamber formed by an insulating frame and positioned between the anode and the cathode, the insulating frames along the periphery are provided with ports for the inlet and outlet of hydrogen, oxygen/air and electrolyte and with channels connecting the ports to corresponding chambers. The ports and channels are positioned on the upper and/or the lower sides of the insulating frames, and the current collectors are brought out of the FCs through the lateral sides of the insulating frames. The ports for the inlet of hydrogen into and outlet from the anode chambers are positioned on the upper side of the insulating frames. The ports for the inlet of oxygen/air into the cathode chambers are positioned on the upper side of the frame, and the ports for outlet of the oxygen/air are positioned on the lower side of the insulating frames, wherewith the ratio of the areas of the ports for the outlet and inlet of oxygen/air is from 1.9 to 2.2. Ports for the inlet of electrolyte into the electrolyte chambers are positioned on the lower side of the frames, while ports for the outlet of the electrolyte are positioned on the upper side of the insulating frames, wherewith the ratio of the areas of the ports for outlet and inlet of the electrolyte is from 1.7 to 2.0. Each of the ports for the inlet and outlet of electrolyte is connected to the electrolyte chambers by two arched channels, wherein the ports for the inlet and outlet of the electrolyte and the arched channels encompass all the remaining ports along the external perimeter, forming a thermal screen. Service access ports, connected by channels to the anode chambers of the fuel cells, are made on the lower side of the insulating frames. An FC battery is created on the base of the aforesaid modules.",
