Abstract: The present technology relates to an information processing terminal, an information processing method, and a program that make it possible to easily operate multiple devices configuring a group in a sense of feeling similar to that when a device of a single piece is operated. The information processing terminal according to one aspect of the present technology causes a selection screen for an operation target to be displayed, the selection screen including information concerning a group including multiple devices selected from among devices registered in a server and information concerning the devices of a single piece that do not belong to the group, and requests the server to collectively control the devices configuring the group according to a selected operation target and control the devices of a single piece. The present technology can be applied to a system in which devices connected to a network are controlled.

Abstract: A fuel cell comprises: a membrane electrode assembly configured to have an electrolyte membrane joined between an anode electrode and a cathode electrode; a flow path-forming member configured to form a flow path that is adjacent to one electrode out of the anode electrode and the cathode electrode and makes a flow of a reactive gas to the one electrode; and a plate-like member made of a material of blocking the reactive gas and stacked on a portion of a flow path-side surface of the one electrode to be adjacent to the flow path. The plate-like member has a gas permeation structure allowing for permeation of the reactive gas in a part where the anode electrode and the cathode electrode are placed in a stacking direction of the plate-like member on the one electrode.

Abstract: The fuel cell system 1 has a reformer 2 and a fuel cell 3. The reformer 2 has a reforming reaction channel 21 that generates a hydrogen-containing reformed gas Ga and a heat exchange channel 22 for heating. The fuel cell 3 has an anode channel 32 to which the hydrogen-containing reformed gas Ga is supplied, a cathode channel 33 to which an oxygen-containing gas Gc is supplied, and an electrolyte 31 formed between them. The electrolyte 31 is a laminate of a hydrogen-separating metal layer 311 and a proton conductor layer 312. The fuel cell system 1 has a cathode offgas line 46 for feeding the cathode offgas Oc discharged from the cathode channel 33 to the reforming reaction channel 21.
