## Abstract

A system and method to handle urine includes collecting urine using a pad or garment, exposing the urine to an aluminum alloy to generate hydrogen gas and heat in an exothermic reaction, and storing the hydrogen in a sealed chamber.

## Claims

### Claim 1

A system, comprising:
a urine receptacle adapted to be worn as underwear on a genital region to remove urine from a person, the receptacle including one or more drain channels and a thermal barrier, the one or more drain channels coupled to one side of the thermal barrier to protect the person during a trip;
a sealed chamber coupled to the opposite side of the thermal barrier and having a metal evaporator with an alloy therein to generate hydrogen gas from the urine;
a fuel cell stack configured to receive the generated hydrogen gas from the sealed chamber;
an energy storage device to store energy from the fuel cell stack;
a biosensor powered from the energy storage device; and
a pump coupled to the urine receptacle and the sealed chamber to remove the fluid away from a skin of the person and dispose the urine to the alloy to generate hydrogen gas in the sealed chamber.

### Claim 2 (depends on 1)

The system of claim 1, wherein the alloy comprises a nano-structured magnesium or manganese alloy.

### Claim 3 (depends on 1)

The system of claim 1, wherein the alloy comprises a nano-structured aluminum alloy.

### Claim 4 (depends on 1)

The system of claim 1, wherein the aluminum alloy comprises an anodic matrix including aluminum, an aluminum alloy or an aluminum-based composition; and a cathodic disperse phase comprising a second metal, second alloy or other second metal-based composition selected from the group consisting of: tin (Sn), magnesium (Mg), silicon (Si), bismuth (Bi), lead (Pb), gallium (Ga), indium (In), zinc (Zn), carbon (C), and mixtures and alloys thereof wherein said cathodic disperse phase forms galvanic couples with the anodic matrix and produce hydrogen gas when said galvanic metal microstructure contacts the urine.

### Claim 5 (depends on 1)

The system of claim 1, further comprising a power converter coupled to the fuel cell stack to regulate power to a load.

### Claim 6 (depends on 1)

The system of claim 1, wherein the energy storage device includes a supercapacitor or a lithium battery.

### Claim 7 (depends on 1)

The system of claim 1, wherein the biosensor is configured to detect a glucose level or a cholesterol level.

### Claim 8 (depends on 1)

The system of claim 1, wherein the biosensor is positioned in the receptacle to detect a heart rate, a respiratory rate, a temperature, and an activity level from a crotch area.

### Claim 9 (depends on 1)

The system of claim 1, wherein heated air is generated as an exothermic reaction to form hydrogen, comprising a garment with channels in the garment to receive urine and channels to provide heated air to warm or dry the garment.

### Claim 10 (depends on 1)

The system of claim 1, wherein the biosensor is configured to detect blood pressure level.

### Claim 11 (depends on 1)

The system of claim 1, further comprising a camera coupled to one of the drain channels to detect urine color level to determine health condition or a stone particle in the urine.

### Claim 12 (depends on 1)

The system of claim 1, wherein the alloy comprises a dissimilar metal in contact with aluminum so as to cause galvanic corrosion.

### Claim 13 (depends on 1)

The system of claim 1, wherein the alloy is milled.

### Claim 14 (depends on 1)

The system of claim 1, further comprising an optical blood pressure measurement sensor coupled to one of the channels.

### Claim 15 (depends on 1)

The system of claim 1, wherein the receptacle comprises a multilayer assembly including a urine drain channel and a heated air tubing.

### Claim 16 (depends on 15)

The system of claim 15, comprising a fan coupled to the heated air tubing and a temperature regulator coupled to the fan.

### Claim 17 (depends on 1)

The system of claim 1, comprising a processor or a neural network coupled to the energy storage unit to process data from a sensor configured to be coupled to the skin.

### Claim 18 (depends on 17)

The system of claim 17, wherein the sensor determines heart rate and blood flow velocity.

### Claim 19 (depends on 17)

The system of claim 17, wherein the sensor comprises an optical sensor whose output is calibrated against an approved blood pressure monitor and blood pressure is estimated during operation.
