Batteries with a safety mechanism adapted to protect against tissue damage and/or electrolysis when the battery is exposed to an aqueous solution or a wet tissue.

Battery with safety mechanism

The invention is directed towards a battery condition indicator. The battery condition indicator includes at least one indicator electrode, a counter electrode for the at least one indicator electrode, and a separator that is combined with an electrolyte. The at least one indicator electrode is in electrical connection with a first terminal of a battery. The at least one indicator electrode includes at least one redox material. The counter electrode is a second terminal of the battery. The separator that is combined with electrolyte is positioned between the at least one indicator electrode and the counter electrode.

Battery condition indicator

Charging at least one rechargeable battery includes regulating a voltage applied to the at least one rechargeable battery by coupling a circuit between an output of a rectifier circuit and the at least one rechargeable battery, limiting the charging current to be within a first predetermined range and when a predetermined battery charging voltage is reached, dropping the charging current to be within a second predetermined range.

Household device continuous battery charger utilizing a constant voltage regulator

Fuel sources, fuel cells and methods of operating fuel cells are disclosed. In one aspect, the invention features a fuel source for a fuel cell, including a housing made substantially from a fuel-permeable material, and a fuel in the housing.

Fuel sources, fuel cells and methods of operating fuel cells

A hydrogen generator includes a housing, a solid hydrogen source disposed within the housing, and an inlet configured to guide a fluid to contact the solid hydrogen source. The inlet can contact a wicking region. The wicking region can include a wicking material that has an affinity for the fluid. The wieking material can include a hydrophilic material. The housing can include a hydrogen gas outlet. The hydrogen generator can include an end cap at one end of the housing including the inlet and the hydrogen gas outlet. The hydrogen gas outlet can include a gas permeable membrane. The inlet can be fluidly connected to a fluid control system configured to control fluid flow rate to the solid hydrogen source. The generator can be portable.
