Abstract: A fuel block system which includes a solid fuel. The solid fuel includes one or more of the following: a biomass or a charcoal generated from a biomass; the solid fuel is configured to release a gaseous and electrochemically-active fuel when exposed to heat.

Abstract: A system includes a fuel cell having a fuel electrode and an oxygen electrode. A shield is configured to be on the oxygen electrode side of the fuel cell and an air chamber is configured to be on the oxygen electrode side of the fuel cell. The air chamber is formed at least in part by the shield. A fuel chamber is configured to be on the fuel electrode side of the fuel cell where the fuel chamber is configured to hold solid fuel.

Abstract: A system for generating electrical power includes a fuel storage container having an inside and an outside including a wall including a heat conducting region configured to allow heat from an external heat source to be conducted into the fuel storage container. The system further includes a fuel cell region associated with a fuel cell having two sides, one side of the fuel cell exposed to the outside of the fuel storage container and one side of the fuel cell exposed to the inside of the fuel storage container, wherein the wall is configured to isolate the inside of the fuel storage container from the environment outside the fuel storage container. The system further includes an opening for receiving a fuel load for storage in the fuel storage container, the fuel cell having two sides, and an electrical connection providing access to power generated by the fuel cell.
